Part# UPFORD - V10 Power Upgrade

Devices now come pre-loaded with your custom tune! No need to update the device with your computer! This does add 1 day lead time in most cases.


UltraPower Custom Tuning is hands down the most cost effective and noticeable performance modification you can make to your Ford 6.8L V10 powered RV. From the factory, the V10 engine's power is de-tuned and the constant transmission shifting is annoying. One of the most noticeable differences from stock will be the elimination of instant downshifts that occur at even the slightest of hills. Your RV will now be able to maintain higher gears without the unnecessary screaming of the engine! This alone makes a great deal of difference in driving comfort. Throttle response is greatly improved and merging onto the freeway will be much less stressful. If even more power is desired, UltraPower Custom Tuning works very well in conjunction with aftermarket exhaust and air intake, such as the Banks PowerPack.

While some tuners rely on "canned" tune files, all of our tunes are tailored specifically to YOUR RV. We require your VIN so that we can pull up your vehicle specifics and make a tune that is truly customized to your RV. We used to require the device be sent and a strategy code read from the ECM, but we now have the capability to retrieve the strategy code with your VIN! This means the device will come pre-loaded with your custom tune, no need to plug it into a computer!

I have a v10 in my Fleetwood Bounder. Can this tuner be used on my RV or would this be illegal in Calif. because of smog requirements ?
( Bud Greer, 10/20/2020 )
Bud, you are not supposed to use the tuner in California, that is the official answer. The tune can be installed and removed with the device, so if you travel, it could still be used... ( Support )
I have a 2015 Ford F550 with the diesel engine, will this work? ( Jim Giffin, 10/20/2020 )
Jim, the UPFORD tuner is only for the gas v-10 models  ( Support )

Hi john, I see to purchase the tuner is 499.00 if I buy a knn intake at the same time will the programmer come set up for the new intake?

What is the 200.00 for? retune for new parts? Would I need to purchase that along with the programmer?

Can I expect factory reliability as far as changing elevations? Driving from say california at 0 sea level then driving to colorado mountains?
( Kegun Bren, 09/28/2020 )
Yes, if you purchase with an intake or let us know that you have one we will tune accordingly. The $200 tune is for folks that already own an SCT X4 tuning device and only want one of our custom tunes. We do not charge to retune for small tweaks to the original tune. The reliability will not change from factory standards. ( Support )
Is your unit compatible with a recently installed Banks Power Pack with Chip installed..............or are they doing much the same thing ? I don't want 2 computers fighting / confusing each other

You say it plugs into the OBD2 diagnostic port. To get a Smog Check if the technicians just plug into the OBD, it gives a "No Communication error" unless they also hook up to the Coach battery, then it reads fine. Is this lack of power to the OBD on my rig going to be an issue ?
( Scott Boyer, 09/26/2020 )
The "chip" in your PCM is the old way that you used to modify the parameters in the computer. Now we all use flash programmers which would interfere with the chip. It does sound like you aren't getting power to the proper pin on the OBD2 plug. I do not have a wiring diagram so I am unable to tell you for certain where to check for that power. ( Support )
How is the unit connected to the rv engine diagnostics?
( David Higgins, 09/22/2020 )
The handheld unit plugs into the OBD2 diagnostic port. This port is typically mounted to the right hand side of the steering column. There are some body builders that will move the plug to a more convenient location but that is where Ford puts it when they send the chassis to the body builder. ( Support )
I have a 2001 dynamax c220. Lovely RV. Looking to tow my race car around the country. How would your product benefit my otherwise perfect running v10? I haven’t towed with it yet as I’ve only had it for a few days but I can see the need for improvements over stock

( Michael Wah, 09/20/2020 )
The custom tune is going to improve throttle response, horsepower and torque for pulling hills and also greatly improve the transmission shifting characteristics.  ( Support )
I'm thinking about your V10 Ultratune and the Banks Ram Air filter assembly. Your dyno charts show horsepower for the 2018 F53 at a something less than 240 and torque at ~320. I'm assuming this is rear wheel horsepower. Your chart for the 2014 E450 shows horsepower and torque significantly higher than the 2018 F53. I believe that Ford reduced the horsepower and reduced the torque peak RPM when they went from the 5 speed to the six speed transmission. Can I expect the peak horsepower to be an additional 73 and torque ~56 ftlb the rear wheels (plus the benefits of the ram air inlet ~10hp and 15lbft)?

Does this also affect the downshifting on downhills for engine braking? I'm always concerned about over revving since there is no redline on the tachometer.

One more question. You show the 'SCT' reading out rpm, etc. is the same instrument as the V10 ultratune and part of the kit? Is the suction cup accessory for that as well?
( Loyal Shawgo, 09/13/2020 )

All of our dyno graphs are measurements at the rear wheels, whereas Ford's advertised measurements are "flywheel," meaning engine disconnected from any running gear. The reason for the horsepower differences between the 2014 and the 2018 is because of the type of transmission. On the 2014 we are not able to put it in 4th gear which is 1:1 engine to transmission ratio. We have to run in 3rd gear which adds a multiplication of power thus showing different #'s. The most important thing is the apples to apples comparison. 

We generally do not remove the down hill grade brake feature when in tow/haul mode, as it will help you with staying off the service brakes as much.

The SCT X4 device will display available engine parameters include engine coolant temperature, battery voltage, intake temperature, spark advance etc, it does not come with the suction cup mount but that can be purchased separately.

I am torn beetween your tune and 5 star can you tell me why yours is better. ( Eric Siedentopf, 09/03/2020 )
All of our tunes are 100% custom to each vehicle. I believe 5 Star Tuning uses templates for each vehicle that allow them to have tunes pre-loaded to their devices. You will see great improvement with either of us but of course we feel that we provide better RV specific tuning. ( Support )
I just bought a 2009 Winnebago Adventurer with a V10 and drove it from Denver to St. Louis. I couldn't stand the constant shifting from 5th gear to 3rd gear going up hills. I had to turn the cruise control off more times than I can count. I'm ok with the RV downshifting to 4th gear at 3,250 - 3,500rpms, but 5,000+ rpms in 3rd gear seems a little extreme, especially since max horsepower is at 4,750rpm. Will this product stop the transmission from shifting to 3rd gear on a long hill? I only want to downshift into 3rd gear if I'm climbing up a mountain. ( Michael Kiel, 09/01/2020 )
The tuning will definitely reduce the frequency of downshifts. The downshifts will occur with a higher percentage of throttle so when you really need the downshift, such as on a long uphill, it will still downshift to the appropriate gear but it will not "hunt" for the gears nearly as much. ( Support )
I have a 2018 freedom elite motor home class c, on an E450 chassis, with the v10. My question is, how much hp and torque can you put in the pre programmed unit without harming or overheating the engine?? Thank you Larry ( LARRY Davis, 08/27/2020 )
We are able to safely gain 43 horsepower and 47 lb-ft torque. ( Support )
We have a 2001 Winnebago 32V that works well below 3500’. It has Banks kit, exhaust, transmission command, fresh air inlet, and computer chip.
Sometimes it won’t down shift, and it works ok, but on hard climbs it doesn’t keep speed up.
Will this help get us up mountains and shift better
( Thomas e Meixner, 08/18/2020 )
Our custom tuning would take the place of both the "chip" and the Transcommand unit. You would see better performance and shifting than what you currently experience, however, it would not be as big of a difference as someone who was upgrading from stock so keep that in mind. ( Support )
2020 Entegra Vision 29F. I see the F53 listed, but do not see any reference to 2020 model years. Confirming this unit will work with my 2020? ( Steve, 08/12/2020 )
As long as it is a V10. We do not yet support the new 7.3L V8. ( Support )
2019 F450, could be a 2108 chassis? Can I use this to enable day time headlights? ( Jason Sylvester, 08/10/2020 )
No, we do not have the ability to do this in the programming. ( Support )
Does this require using premium 91 gas? ( Josh, 08/05/2020 )
No, we tune to 87 octane unless otherwise requested. ( Support )
How does this tuner actually work with my Motorhome. Does it do something to the engine, transmission, or both? I'm ready to purchase but would like a little more information. ( Keith J Richoux, 08/04/2020 )
The tune makes changes to both the engine and transmission settings in the Powertrain Control Module. This module controls both the engine and transmission so there is only 1 load for both. ( Support )
What is the benefits of your tuner vs a 5 star tuner? ( Stephen Carey, 07/28/2020 )

Typically our tunes will increase the horsepower and torque more than 5 Star's. We both greatly improve the shifting and throttle response.

( Support )
I have a 99 fleetwood v10 southwind class A. Can I expect the average gains of 50 hp and torque with the benefits of everything else mentioned. Throttle response of shifting etc. are these realistic gains worth the 500$ an does the tuner monitor anything. Or is it just a plug-in downloaded the tune and done ( Dan, 07/24/2020 )
A 1999 V10 would have the 2 valve head design which we see gains of 43 HP and 47 lb-ft torque. We constantly get feedback that the cost of the tuner is well worth it for the benefits that it provides without any real labor involved. The SCT X4 device does have monitoring capabilities, so if you are wanting to use it as a scan tool you can. ( Support )
I just bought the Ultra RV tune for a stock F53 based RV. If I install the Banks Ram Air kit, will I need another tune program? Then, if I install the Banks header kit ($1799), will that require another tune program?

Tom Spurlock
( Tom Spurlock, 07/08/2020 )
We will only need to re-tune for the long tube headers, there is no charge for this. ( Support )

I have 2013 Hurricane RV F53 and did installed a 5 star tuning in 2014, so I have the early model SCT X3 device. Can I use this and
just buy the tune only?
( Fidel Avanzado, 06/14/2020 )

Yes we have just the tune available to purchase here: https://www.ultrarvproducts.com/Ford-V10-UltraPower-Tune-Only

You can still enter in the X3 serial, we can make a tune for that still.

( Support )
I have a 2020 Tiffin Allegro Open Road V-10 Gas.

I read on one of your reviews that a customer with a 2020 Newmar (similar application) - needed a "STRATEGY CODE" ?

Will you require the same for my RV as well?

thank you

( KEN LEE, 06/04/2020 )
We no longer need the strategy code before making your tune, just the VIN for the chassis. ( Support )
How much HP and torque would your product add and does it void the warranty. Mine is a Phoenix cruiser 2910t year is 2017. ( John, 06/03/2020 )
We would gain you 43 horsepower and 47 lb-ft torque with our tune. As far as your warranty goes, it will not void it automatically. First of all, when you tune your vehicle the, SCT Tuner stores the stock file onto the device. When you are going to go in for Warranty work, you can return the computer to stock settings. The SCT tuner, unlike other brands, leaves absolutely no footprint in the PCM history. In order to deny any warranty repair the dealership has to prove without a doubt that the tune was the cause of the damage. We can thank the Magnusson-Moss Warranty Act for this.

v-10 , 2004 f550 gulfstream motor hm , 24000 loaded. pull a 20 ft boat at times. what can a chip improve and do you have opion between new anti sway torsion bars or air bags or summo springs. ( michael faker, 05/15/2020 )
The tuning is the best upgrade you can make to improve power and shifting. We prefer anti-sway bars over SumoSprings as they make the chassis ride even rougher than they already do and air bags tend to actually make the RV handle worse. ( Support )
I’ve read that the newer Ford V-10’s have been tuned better from the factory, thus the difference using the UPFORD doesn’t give as a dramatic performance upgrade. I have an E450 v-10 on a 30’ Jayco class C. What kind of hp increase can I expect? More annoying is the trans shift up even the mildest incline. Thank you for your response. ( Steve, 05/07/2020 )
The power output of the 2V V10 found in the E-Series has not changed for some time but Ford has made incremental changes to their base tune to improve driveability. Even so, there is still a substantial amount of performance to be had with gains of 43 horsepower and 47 lb-ft torque and much improved shifting characteristics. ( Support )
Does this package require a FORD mechanic to properly install. ( William Hunt, 04/08/2020 )
William, No, basically you just plug it in and press a couple of buttons. ( Support )
Does your package require a certified FORD dealership to install? ( William Hunt, 04/08/2020 )
No, most folks are perfectly capable of installing it themselves. Very straight forward process.  ( Support )
I interested but not clear what if the suction cup accessory for? Does the unit remain plugged in at all times? ( Jay, 04/04/2020 )
No, the suction cup mount is simply for those that want to keep the unit plugged in to monitor engine data. You can load the tune and unplug the device, which is what the majority of our customers do. ( Support )
I have 2006 Ford E450 10 cyl 14ft U-Haul van that I purchased for towing my race car. Vin number is 1FDXE45S56DA65635. Will your system work with this vehicle, what improvements can I expect, and can you send the device pre-loaded? Thanks! ( Steven G Lisa, 03/01/2020 )
Yes, we can tune your vehicle, that is not a problem. Gains would be approximately 40 horsepower and 45 lb.-ft. torque and improved shipping. We would only be able to send the device pre-loaded if you have the means of pulling the strategy or calibration code with a scan tool. ( Support )
I have a 2015 F53 V10
How does a tune effect tow/haul mode?
( Brian Fullerton , 02/24/2020 )
Unless requested to have something changed in tow/haul mode, we do not make changes to the shift points in this mode. ( Support )
In relation to the UPFORD - Ford V10 Ultra RV Tune do I understand it correctly that I need a PC laptop with me to install the software? I live in one state and the RV is in a different state and I do not plan on taking the laptop.
( glenn wade, 02/21/2020 )
Yes, a PC is required to transfer the e-mailed tune file to the device. Most Ford scan tools will read the strategy code, they might call it a calibration ID or something else though. If you can get that code beforehand, we can make the tune, load it to the device and send it ready to go, no computer required. ( Support )

Considering using the Ford V10 Ultra RV Tune in a 2013 Class C 23' motorhome, Ford v10. Would I need to burn premium gas or could I stay with regular? Internet is not definitive. The motorhome shifts are probably the main issue I would like to change and of course if I can get other benefits, great!


( glenn wade, 02/17/2020 )
The tune is designed to work with 87 octane fuel, no need for premium. ( Support )
a few years back, I needed to get a new ecm from ford, I had to wait over year to get one ue to lack of available parts for the ecm. Could not find a rebuilt or used one anywhere in America, believe it or not! after I got my truck back, it ran smooth and started perfectly, but the CEL was on due to canister vent valve, I eeentually bought one, installed it, and still has light on. The power is much less than before the new ecm, my mileage has dropped from around 2 to around 8, sometimes 6, will your tuner turn off the CEL" on start up" like my edge juice in my 07 duramax which is deleted?, I am guessing the ford house detuned my truck, will your tuner restore the power I once had and hopefully the mileage? ( rich engstrom, 02/05/2020 )
We are not able to do anything with the emissions systems, including turning off codes. We tune the ECM based on the strategy code that is stored in the ECM, which if the truck was programmed from Ford incorrectly to begin with, may not net the results that you want. I would take the truck back to Ford and verify that they have the correct calibrations loaded for your VIN and have them run diagnostics on that code to find out if there really is an issue or if there is something corrupt in that ECM. ( Support )
I have access to an OBD2 scanner that can display the strategy code. If I provide that code at the time I purchase the unit can it be programmed and ready to install when I receive it? ( Fred R, 02/01/2020 )
Yes, just leave that information in the comments and we can pre-load the device with your custom tune file.  ( Support )
I have noticed engine ping when accelerating and when towing. I have increased the octane to 89 with slight improvement but the ping continues. Will the investment in UPTuning my 2017 Ford 6.8 V10 stop the ping and allow me to use 87 octane? ( Ronald R Francoeur, 01/02/2020 )
If you are pinging with everything stock, there is an issue that needs to be addressed. With the custom tuning, the spark is further advanced and would just exacerbate the issue. I would try cleaning or replacing the mass air flow sensor first. ( Support )
I am a full-timer and have a 2019 Newmar Canyon Star 3924 (a gasser).

Why buy your product versus, say, the 5 Star device?

I will be now be towing a 2019 2-door Wrangler Sport A (JL) behind me since I just had a tow system installed. Will it matter if I sometimes do not tow my Wrangler on some trips? In other words, is your device custom programmed for always towing the Wrangler or is towing the Wrangler a moot point?
( Karl, 12/30/2019 )
We tune each vehicle individually while 5 Star uses a "canned" tune that is pre-loaded to the device so that they can tune multiple vehicles without having to do each tune manually. The result is less work for them, but the gains are not as good. We tune for optimized performance, whether you are towing or not. If you wanted something "tweaked" later on, such as a certain shift point, we can make those corrections and update you for free. ( Support )

The tuner if I purchase just that and decide to upgrade my air intake and exhaust is there a change in the tuning ? If so is there a charge to upgrade the tuner ? ( Matt, 10/28/2019 )
The only modification to the exhaust or air intake that would require a change in the tune would be if you added long tube headers. There is no charge for updating the tune. ( Support )
I have a 2011 Jayco grayhawk. much to my surprise it has banks headers on it, which I had to change the passenger side exhaust gasket on it. very hard to do, not much room. it has the v 10 2v. engine. the rig does very well now with the headers on power and hill climbing, but does require some down shifting. how much will this improve my performance. thanks. ( tom , 10/07/2019 )
The tuning will make a big difference! Not only will it make more power but it will also dramatically improve the shift patterns, which is a common complaint. ( Support )

I have a 2014 Forest River FR3 30DS class A and was about to buy the 5 Star tuner. what is different about your tune? ( adam harris, 07/24/2019 )
Both 5 Star and us use the same hardware (SCT) but our tuning calibrations are of our own creation. From what I understand, 5 Star does not do much to increase power throughout the RPM range, only at wide open throttle. They do not map the ignition timing or fuel tables, which we do. All of our tunes are custom to the vehicle whereas their's are pre-loaded to work on a range of vehicles. With either ours or theirs, you will experience better shift points. ( Support )
I'm in the process of purchasing a new 2018 RV that has a Ford Triton V10 engine. Will "tuning" the engine with this device/software void the Ford factory warranty? If I need to take the RV into a Ford service center, do I need to return it to "stock" before taking the RV in for service? Would it be better to wait until the engine is no longer under warranty by Ford before utilizing this device? I would really like to get the benefits of this device without having to wait for the Ford factory warranty to expire. BTW, I live in a state that has NO vehicle emissions inspection requirement. Thanks in advance for any info/suggestions you can provide. ( Todd, 07/07/2019 )

My husband and I are elderly and we are wondering how hard is it to install this on our 2016 thor 31W RV? If we bought it, and could not figure it out, would we be able to return it for full amount of purchase. ( Judy Lawrence, 07/06/2019 )
We offer the option of receiving the device, plugging it in and simply going to a screen that shows the VIN and Strategy code, writing the Strategy code down and then mailing us the device back (choose the option for including a return label) and we will do all the steps that require a computer. Once we load the tune and mail the device back, you will simply plug it back into the vehicle and load the tune which is very basic and easy to do, even without any computer skills. ( Support )
Our 2000 tropical f53 motorhome v-10 has a banks Trans Command which I installed 16 years ago and I am wondering if I should remove it if I go with your Ultra device, by the way a friend install one and left for Alaska and called and said that is doing what it says it would. ( Buck Sloan, 06/26/2019 )
The Transcommand would be interfere with our tuning as we make changes to the transmission that would cause it to shift too firm with the Transcommand installed. We recommend uninstalling the Transcommand prior to loading our custom tune. ( Support )
If a buddy already has a sct tuner can I use it and buy a tune from you and it work? ( Kevin, 06/19/2019 )

How do you go back to stock tuning if you were to sell your motor home? ( Murray Rabalais, 06/09/2019 )
Once you’ve programmed the ECM with our tune, it creates a new option when you next go to program it, which is the return to stock function. It will load the previously saved stock file and unmarry the device from the vehicle.  ( Support )
It's our understanding that by paying the return postage cost back to you that the final product you ship to us will have all of the correct information loaded into it. If we're correct, then we can skip the down loading process? We're working with a 2019 Four Winds 31W coach and aren't overly impressed with the performance. We are "old school"; change the distributor advance spring and a high performance electronic ignition module and hang on!! Any improvement from stock would be welcomed.
David L. Cavin
( David L. Cavin, 05/17/2019 )
That is correct, if you choose to include a return label then all you have to do is get us the strategy code, send the device back and we will load the tune file. From there, all you have to d when you receive it back is to plug it into the vehicle and load the tune. ( Support )

My only issue is the down shirt protocol while in cruise control. The double down shift under load is the issue. Does your software change this protocol or is the improved shifting do to the increase in power? I currently do not use cruise In the hills or mountains because the constant throttle method gives a nice down shift and avoids the 4000+ rpm.

Thank you,

( Robert Berghuis, 04/05/2019 )
The cruise control downshifting is addressed as well as we can. There is only so much that can be done as cruise control's job is to maintain a set speed and Ford does not allow it to be adjusted beyond a certain point. For this reason, it is not advisable to use cruise in the mountains but you will now be able to to use it on more moderate hills/inclines without the instant downshifting. ( Support )

I have a FR3 30DS, towing a 2d Jeep Wrangler. when I get this program installed, will I still but the transmission in "tow mode" ( Grady, 03/19/2019 )
If you want the transmission assisted braking going downhill then you will want to put it in tow/haul. As for normal driving, you can play around with both modes to see which you prefer. ( Support )
do you have products for this class-c? ( THOMAS Dunlavey, 03/14/2019 )
Yes our UPFORD programmer will work on your 1999 E-250. ( Support )
You would purchase this product, UPFORD. We will program it specifically to your vehicle after you receive it and give us the strategy code. The vehicle can be returned to stock settings at any time. ( Support )

1. Can this be sold/installed in California?

2. Who would one use to program the devise? A Ford dealer? An RV repair shop?
( Wayne, 02/08/2019 )

The SCT X4 comes with pre-loaded tunes for many Ford vehicles, such as Mustangs, F-150's and Powerstrokes. The devices have a warning that they are not for use in California but that is simply because these pre-loaded tunes for other vehicles are not emissions compliant with California laws. We do not use these pre-loaded tunes for RV's so what we are loading into your engine computer is custom to the vehicle and will pass California emissions tests. 

Most folks can load the tuning themselves or have a friend help. It only requires a Windows computer and an internet connection to download the tune. No special tools or mechanical abilities are necessary.

Will performance chip work for 2019 Ford V10? ( DAN SEID, 01/28/2019 )
Yes it will.  ( Support )
What data does this device allow you to access while driving? Can you see temps of oil, tranny,water? Does it provide mpg? Thanks ( Rick, 01/14/2019 )
It varies depending on year but typically it will display engine coolant temperature, battery voltage, RPM, intake air temperature, engine load, long & short term fuel trims, mass air flow, spark advance, transmission temperature, throttle position and vehicle speed. Some vehicles may offer more or less but this is typical. It does not do MPG readings, I recommend the ScanGauge2 for monitoring. ( Support )

I recently purchased a 2019 Entegra Vision 29S RV equipped with the Ford V10 Engine. Will this device affect the Ford Warranty? ( Jon Dunn, 01/08/2019 )

Ultra RV is committed to providing quality custom tuning that is safe to use. Our custom tuning does not cause damage to a vehicle when used as intended and should not void your vehicle’s manufacturer’s warranty. However, the reality is that many dealerships have been known to improperly void warranties on vehicles that use aftermarket products as a matter of policy. This applies to those aftermarket products that produce horsepower, such as performance enhancement “chips,” modified intake manifolds, or aftermarket exhaust systems, regardless of product brand.

Consumers of aftermarket products are protected by the Federal Magnusson-Moss Warranty Act. The Act provides that if something breaks on your vehicle and you take it in for warranty repair, the dealer must honor your warranty unless whatever modifications you have added to your vehicle directly caused the problem in question.

In order to understand your rights under the Federal Magnuson-Moss Warranty Act, please see below excerpt.

When accessorizing your vehicle with aftermarket parts, your warranty claim cannot be automatically denied, nor can your warranty be voided, if you install non-OEM parts in your vehicle. The burden is on the dealer to prove the aftermarket parts caused the failure. For example, if your windshield wiper motors fail, your vehicle’s warranty claim can’t be denied because you installed aftermarket performance programmer, tuner, chip, etc. Similarly, if a wheel bearing fails or a fan belt snaps and you have an aftermarket exhaust installed, the dealership would have to prove the exhaust system caused the bearing failure or the belt to snap in order to deny a warranty claim. In these types of scenarios, the dealership should have no reason to deny your claims.

In addition to the Magnuson-Moss Warranty Act, you also have SEMA (Specialty Equipment Market Association) working to protect your rights. Because SEMA represents U.S. aftermarket wholesalers, retailers, distributors and manufacturers, they often keep car manufacturers in check by supporting legislation that prevents dealership service providers from denying warranty coverage. This means dealerships have become less stringent when it comes to aftermarket parts that modify performance or suspension.

Average mpg is 8 for the last 2 years. Approximately what will be the improvement in mpg with this controller?

( KEN BURNS, 12/27/2018 )
We can only promise improved power and shifting. Most times there is a gain in MPG but it's such a variable in RV's that we can't tell you that you will. ( Support )
With this turner, can you manually shift all 6 gears? For example, can you hold the tranny in 5th while towing. ( Al, 12/24/2018 )
Unfortunately we do not have a way to manually control all 6 gears. We can promise that it will hang in each gear a lot longer than with stock programming. ( Support )
1) Does this have an adverse effect on emissions? In other words, are you "Pulling a Volkswagon?"
2) My primary need is fuel efficiency. Don't need more power. Can you taylor a program to conserve fuel by (a) allowing slight slowdown on climbs and (b) allowing slight speedup before engine braking on descents?
( Geoff Wilson, 10/12/2018 )

1.) We have not had any issues with our customers (even CA customers) passing emissions testing. We DO recommend returning the PCM to stock just to be sure as it's a quick, simple process.

2.) We can't guarantee fuel mileage improvement on an RV. We can guarantee much improved shifting performance and power. The things you are asking about would not really be a programming feature, you'd have to still control those things with your right foot ;)

( Support )
are the improvements noticeable with the stock air intake and a stock headers / exhausted. Will you ship to CA. Do I need to have a mechanic install this program ?

Thank you,
( Fred, 09/30/2018 )
Fred, the improvements are very noticeable with all the factory components installed. We do recommend the Banks headers to get the most out of the engine, but not needed for a great power gain from just the programming. ( Support )
Just purchased a 2018 Forest River Sunseeker RV Ford E450 and V10 engine. What performance options are available for this unit.

We recommend our UltraPower Custom Tuning  ( Support )
How much on the average will this improve my mileage? ( Steven Andrews , 09/07/2018 )
While we don't guarantee any fuel mileage increase, most of our customers will see a slight improvement. I wouldn't say much more than maybe 1/2 MPG increase. ( Support )
Is the Ford V-10 ultra power custom turner legal in Ca.? ( Bobby Guthmiler, 09/03/2018 )

I have a 97 FORD E-SUPER DUTY cut-a-way 6.8 V10.

Frist will this tuner work on my RV?

What gains would I see in hp and torque?

Second what else do I need to install to get the max out of the motor safely?

We have 4.63 gear but it is gutless on hills... and we want to pull a small trailer but with way it is now it would be imposable to go over 40 in the hills
( Steven Tice, 08/06/2018 )

Yes our tuner will work on any V10, you just have an early one :)

The gains on your engine would be approximately 43 horsepower and 47 ft-lb torque.

Really the only other modifications you can make would be the Banks TorqueTubes and exhaust.

We are looking at your performance chip for our 2016 Class C Forester with a V-10 engine. the problem has been there since we purchased the unit new. under increased throttle applications the engine downshifts and the engine surges and very slugging. We are presently on a road trip in British Columbia Canada and in the mountains its really bad. My question is will your performance chip help correct this problem hope to hear from you asap before we head back to Ontario at the end of August. ( Harvey Brillant, 07/29/2018 )
Our UltraPower Custom Tuning will help quite a bit with your complaints. Not only will it have more power to climb the hills but it will shift more intuitively and not downshift nearly as often on grades. ( Support )

I have a scan guage attached and I love it. Now with your unit does it have to be attached all the time and if so will it show my mpg, average mpg, rpm, voltage and all that ( John D Maag, 03/10/2018 )
No it does not need to be plugged in all the time. Once you have programmed the vehicle you can unplug and use the ScanGauge just like normal. The SCT X4 device does offer data monitoring but it is not as “simple” to use as the ScanGauge.  ( Support )
Hi: This is our first venture into a class a motorhome. I have always used a tuner in previous class c M/H one a 7.3 2002 and the second a v-10 2011 two valve. The first was a5 star tuner and the second banks. I agree with your comment that the 5 star was better than banks. So my question is as I still have the banks tuner and you said you use the same type thus can you send me the program once I send all info required etc via computer which I can upload to my programmer. This would avoid a lot of issues as I am in canada thus being much easier for me. This would be after payment for your custom tune to my specific unit. I can go and get the vin and anything else you need to start the process if this will work. Thanks Blair ( Blair Bourchier, 02/26/2018 )

2008 Four Winds 31p. Purchased used a year ago, nice ride no power when it comes to any incline. No flexability for down or up shifting the transmission. What will your system do for me, beside the hype being advertised? ( John Ferdig, 06/08/2017 )


The tuning greatly improves the shifting of the transmission. Not only does the added power help it maintain gears, we also are able to calibrate the transmission shift points to more suit the RV application.

i have a 2006 ford f53 i just ordered some parts from you but have a different question. i have purchased the banks sct 7015 and am very dissatisfied with it. i am not noticing any power dif or mpg dif. i have put on over 3000 miles since i install it and nothing seems to have changed. i called banks and they said this system really does not do much for my v10. am i doing something wrong and or can you suggest doing something.
thanks joel
( joel sindelar, 07/17/2016 )


Unfortunately Banks is not too interested in putting much R&D into their Gas RV programming. We use the same device but tune with settings we have found work very well and improve performance, shifting and fuel economy. I would see if you can return the product and switch over to ours which I'm sure you will be very satisfied with.

I own a 2014, Forest River, Georgetown XL . It is 37' 11'' long and has a ford V10, 3 valve engine, on an F53 chassis. Its clear the performance improvements in the 2 valve engine are substantial. But what could I expect in my engine? Also, if down the road I were to do mods like headers and Intake, would I have to buy additional software ?

( Ron Melanson, 03/10/2016 )


Performance gains on the 3 valve V10 are just as impressive as on the 2 valve and the transmission tuning alone makes a great deal of difference. We offer free updates so if you ever do install any additional hardware just let us know and we will make you a revision. 

( Support )

I have 1 2014 Thor Windsport 35E motorhome on the F-53 chassis. Will this tuner fix the radical 5-3 shift on hills and hold it in a higher gear longer when in cruise control approaching hills? Quite a few RV owners have gone with the 5 Star Tuner, what benefits are there to using your product?

( Ben, 01/09/2016 )


Yes, the UltraPower Tuning will greatly reduce the downshifting characteristics of the transmission. Engine performance, throttle response and transmission control will be much improved overall. As a rule we do not compare ourselves to our competitors as what we do is geared specifically to RV's only whereas everyone else focuses on automotive but offers RV support.
