I have a 2001 L21 that I would like to use with my 1979 Camaro. It would be a manual trans install if I can figure that part out. I have the ecu that ran the motor. I was hoping to get it running as is with its factory efi and coil packs. Can you help me perhaps suggest a path that will work if possible?
Thanks,

Hello, I have 1999 C3500 with a 454 and trying to see if your tune will help with the performance of my truck. Currently the Cats are gone and the egr has been deleted. The O2 sensors are still plugged in. For some reason I still have a slight miss and I think it’s because I still have the stock program running with the cats and egr emissions parts gone. Also, the check light is on. Will your ecu help?
( Charlie , 02/23/2024 )
Yes, the tune will most definitely help the performance. The miss could be attributed to still having stock programming but I wouldn't say that for certain. Of course with the tune, we can turn off the check engine light. ( Support )
Is it possible to tune the ECM to get rid of the GM efi system and install an HEI distributor and carb?

-Can you tune the ECM properly for these changes for my specific type of use (low end torque for off road/towing with some street driving)? I would also love to get a few more MPG if possible.
-Can you also reprogram the ECM for transmission changes (quicker/firmer shifts, speedo correct for tires/gears, etc)?
-I’m also interested in the ScanGaugeIII OBD2 Vehicle Monitor. Does it monitor ALL the sensors on the engine including fuel pressure and each individual injector?
Thanks
( Robert, 09/10/2023 )
Yes, we can tune your ECM to accommodate the modifications you plan on making for both the engine & transmission. The ScanGaugeIII will display the available parameters, but the fuel pressure is not monitored by the ECM so it would not give you that. I don't believe it will give you detailed injector information either. ( Support )
Will I be able to further tune the ecm after I get it back?

Hi,
I have a 1997 Chevy Silverado K3500 with the Vortex 7.4L engine and 4L80 Transmission. I'm swapping to a NV4500 manual transmission. I have a whole junk truck to use the parts, but it has less equipment than mine, for example it has no A/C.
I have 3 PCM's available, the Junk Truck PCM, my K3500 PCM and an extra one I bought online before.
Would it be possible to tune the original Manual Transmission base truck PCM to support a fully equipped truck with A/C, power windows, power mirrors etc?
I can share the PCM's service Numbers if that help you determine which PCM will be a better fit.
Thank you!

Good morning
Background: I just recently bought a hypertech programmer for my 1999 (build date 8/98) GMC Suburban 2500 with 7.4L Vortec. I use the vehicle for family road trips and for towing a 6klb boat. I would like to get more power but better economy when towing if possible. I live in AZ and in my county there is emissions testing, so I do not want to change anything that would cause me to fail.
Questions:
1. Is my vehicle compatable?
2. I do not want to have my vehicle out of commission and risk having a ecm get lost/damaged in mail can I send my old one back for the core credit once I recieve the tuned ECM install and verified it works?
3. What HP/TQ/MPG numbers might I expect?
4. What is the process/steps/turnaround to complete
5. What parameters can be changed with your tunes?
*I do not care if the ECM is painted or not if it holds up the process I just want it to be reliable and work.
All the best

( Daniel Wiktorowicz, 09/15/2021 )
1. Yes, your vehicle is compatible.
2. Yes, you can pay the $100 up front core charge and be refunded when you send your original back to us.
3. Typical gains are 40-45 horsepower and 45-50 lb-ft torque
4. Once the order is placed and you have paid for a core, we will program a PCM here and ship it with a return shipping label for your core. Typical turn around is 3-4 days, sometimes quicker
5. We set all the parameters in the PCM, so you will not have a way to make adjustments on your end. The most important changes that are made have to do with spark advance, fueling, transmission shifting and torque management settings. We will set the tune up based on your modifications and requests.

Reading some of your responses I came across one with regards to a 1996.
Can you program for a 96 gmc 2500 suburban 4x4 for toque and HP gains?
thanks

Yes, as long as it is a "J" (8th digit of the VIN) Vortec 7.4L, we can tune it. ( Support )
Can i tell if my RV has this already? Do you have identifying marks on the ECU? Interested, but don't want to buy one to find out i've already got it :D (my unit has 2 previous owners i think...)
Thanks!
( Drewe, 08/07/2020 )
It may or may not have a decal on the ECM depending on if they did a mail order tune or came in to our shop. The only way to know for certain would be to pull the ECM and send to us so we can read it out and check. ( Support )
I have a 2000 C3500 with the 454/L29 and auto trans. The previous owner had the engine rebuilt in 2012 and tells me they installed an RV cam but I am not sure which one. I have the parts list and see one item called 01-412-8 hyd roller cam for $315. They also installed roller lifters, heavy springs and chain/gears. The heads, pistons, and intake are stock. The exhaust does not have CATS with dual to the muffler and single exit tailpipe. I installed a K&N replacement are filter in the stock air box. Installed E3 spark plugs which seemed to help. I tow a large fifth wheel trailer with RPMs between 1800 to 2500 typically. This is a crew cab, 8 foot bed. Is this enough information to create a tune or will you need more information? My goal is to improve torque and trans efficiency then MPG. The tire are one size larger than stock to the speedometer is off a little. When it shows 55 MPH your actually going about 57 to 58 MPH.
Thanks

I have been watching lots of posts and things get carried away very quickly about getting big big hp.
Gettingn very confused over nwhat to do with this information.
We are looking for extra HP/Torque to tow with our dually.ECM mod -Cam-Reworked heads TBI changes ??
Just need to know what works .I realize there is a cost for everything but a pension will only allow for so much..
Would converting to an 8.1 be of hp benefit in favour of tow power

( kenneth a hiebert, 03/07/2020 )
Best, least expensive way to get more power out of this engine is with our custom tune. All other modifications are going to be expensive, labor intensive and still not necessarily yield the same results. Another popular upgrade is changing to Bosch 4 hole injectors. ( Support )
I am doing a full engine swap from a damaged motorhome to my older motorhome. I have a 2000 7.4 engine transmission and full wire harness and ECM from one motorhome and want to put it in my 1995 motorhome. I don’t have the 2000 VIN only the VIN from my 1995. Can you tune my new 2000 ECM and will it work without the original key and ignition harness.
( Rick, 03/01/2020 )
We can tune the 2000 ECM for that engine and I'm pretty sure the ignition harness on that vehicle has no tie in with the ECM. I'm sure there are other differences that would need to be addressed but you should still be able to re-use the original key and ignition harness. ( Support )
Do you folks know of cam upgrades along with tuning that would give power upgrades on a l21 with a manual transmission ?
( Jerry weeks, 02/12/2020 )
We are unaware of any cam upgrades specifically for the L21. That said, the main internal differences between the L29 and L21 is that the L21 has forged pistons and crankshaft. You might be able to run an L29 cam, but you will need to consult an engine builder. We can tune it if you can build it :) ( Support )
Fuel pump doesn't run. I straight wired it to test it and it will run. I replaced the relay to no avail. At the relay the Orange wire is hot with 12 volts continually. The Gray, the green with white strip and the black test grounded. There is a small red wire that has never been connected to anything. The batteries are fully charged and there is 12 volts to the distributor. I sprayed starter fluid in the tbi and it fired up for a few second.
What should I try?

We tune the original black box PCM but do not do the 411 swap. ( Support )
Sorry I don’t have the VIN, the truck is not local, I have a 1998 2500 7.4 Vortec GMC Suburban. As I understand it I do not have the newer 0411 ECM and these have better processing power but need to be repinned. Is it possible to get the newer 0411 with your tune for my truck.

I have a 2000 GMC school bus with the L21 7400 motor. Can you reprogram and net me the same HP & TQ numbers as the L29?
I'm of the opinion that your upgrade would be smarter than the carb, intake, cam, and distributor mods.
( Lyle, 12/18/2019 )
Yes, we can tune your L21 for similar gains as with the L29. We do not, however, have core PCM's for this engine so you would have to send your PCM in for the flash. ( Support )
So I have a 98 K3500 with the 7.4L and I use it mainly for hauling, but I have began to daily it. I have a few questions so bear with me here. Are the tunes generic or do you change different things for different people? I am considering doing an EGR delete and I wasn't sure if this would accommodate that or if it will still throw a check engine light. You claim 40-55hp gains is that something that I will notice drastically or is it more of a subtle power increase? Thank you.

The tuning is custom to each vehicle depending on calibrations, modifications and any special requests. It is quite a noticeable difference! ( Support )
Hello,
I have few questions for k3500 7.4l 1999 first the 45 to 50 hp gains is that on 87octane gas?
The next question could you custom tune ecm for turbo or supercharger with low boost application? And a 5 spd swap?
( James Sinclair, 12/12/2019 )
Yes, all gains listed are with 87 octane gas. We don't however specialize in forced induction applications so we would not be able to help you with that. ( Support )
My question is you claim 40-55 hp gain on the 7.4l , and all the other tuners on the internet only claim 20-25hp gain, will I really see 40-55hp gain with stock engine, exhaust, and air filter? Also how much benefit do you think I would gain by going aftermarket catback exhaust.

98 Single Rear Wheel 3500 7.4 Vortec. Will this correct my RPM gauge issue? Warmed up at idle the gauge is reading 1200RPM then put it into drive holding the brake and it’s reading about 1000RPM. I’m also trying to get more out of this engine without tearing into it so I was just hoping this fixed my gauge as well. Also I want to send you guys mine as core but I wanted to get yours first so I’m not without my truck and if something goes wrong I can plug my factory one back in, so can I wait to send mine till after I get yours?
( Dalen Hale, 10/07/2019 )
The issue with your tachometer would only be fixed if there is an actual issue with your PCM. Is it actually running at that RPM or just showing that? Have you plugged an OBD2 reader into the truck to see what it is displaying for RPM? You can definitely hold on to your PCM, that is not an issue. ( Support )

We have no issues with tuning a higher mileage engine as long as it is in good running condition. We include a data recorder with the ECM for your to record engine data and send to us to verify all engine systems are running efficiently. With our tuning, peak horsepower is at about 3500 RPM and peak torque is about 2500 RPM. You can either pay $100 for the core and then be refunded when we receive back yours or you can send in your ECM for reprogram. Turn around time is 1-2 business days. ( Support )

Hello I have 2000 GMC k3500 Truck. I do some pulling but mainly driving with this truck I have a factory y pipe with no cats and dual 3 inch flowmaster mufflers. And a k and n filter. Truck runs great doesn’t miss or anything just seems to not really have any power at all in 1st gear and alittle more in second gear. I heard these trucks have a torque management system does this computer give my truck back all it’s power? and will it improve my over all power?
( Beau , 05/26/2019 )
Yes you are correct that there is torque management which "pulls" back power when taking off from a stop. We modify this so that it is still "safe" but definitely wakes the truck up. This is only 1 of the many changes that we make with our programming to achieve great power gains. ( Support )

I am considering your tune for my motorhome. I am upgrading the fuel injectors with the new Bosch III's and the plugs and wires.

I plan on a couple of cross country trips this summer before the Banks PPB install, so, should I wait for the tune until after the Banks install or do the tune this year? Thanks
( stephen mills, 02/25/2019 )
If you send us your PCM, our turn around is usually 1-2 days. We can do the tune now with the Banks kit taken into consideration for down the road. It won't hurt anything to run like that. ( Support )

If this ecm has to be reprogrammed in the future do I go to GM Dealer or have to send back to you?? And what is the final cost of your ECM
( Jerry Cable, 05/20/2017 )
Hi Jerry,
Our tuning is custom to your vehicle so if you ever did have a dealer flash the computer it would wipe out the performance settings and revert to stock. There should be no reason to ever need to reprogrammed in the future and if you needed a replacement PCM we can take care of that for you. Cost is $395 plus a $175 core charge which is refundable.

I am considering some performance upgrades to my 2000 Winnebago Brave with the 7.4 liter engine. I would like the biggest bang for the $. Dollar for Dollar, it is highly unlikely that the $2400 for a full blown Banks Power Package would yield the same cost/benefit as say the addition of the UltraPower GM / Workhorse 7.4L (454) Custom Tuning module. I assume the module is a pre-programmed ECM chip that replaces the stock ECM chip. Can I reprogram on the fly as conditions change and performance needs warrant a change?? Or is it what get is all you get? Give me some idea as to what this product does exactly, and how I will benefit from spending $$ on it.
If it is not a driver-programmable module, do you offer a product and which product is better for my application (programmable/non-programmable) as I am planning a cross county trip that will take me over the Rockies and back again?
Thank you for any assistance.
Arnie
( Arnie Bertsche, 03/22/2017 )
Arnie,
I am of the same opinion that the UltraPower programming is going to be by far your best "bang for the buck". It is a re-programmed ECM, either you send yours in or we send you one on a core exchange. We set it for the best performance in all conditions, it is not user adjustable. Gasoline engines do not require different settings for different conditions like a diesel engine does. We gain on average 45-50 horsepower and 50 ft. lb. torque so it will definitely be able to hold the upper gears better when hill climbing and have improved acceleration.
