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?

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.
Purchased a 2016 CLASS a F53 chassis with 6.8L V10 6 speed trans. Does Ultra Power have a tuner yet for this unit. If not when is the anticipated projected date?

As of right now we do not have support for the 2016 models (10th digit of VIN "G"). We are expecting to have support after the first of the year.
What kind of fuel and performance upgrades could I expect on my Winnebago Minnie Winnie 31KP if I purchased this unit?

On your V10 you will gain between 45-50 horsepower and 55-60 ft. lb torque. The fuel mileage increase can vary but typically we see an average gain of .5 to 1 MPG increase.
i have a 2005 coachmen concord will this unit help with power issues v10 motor f 450 chassis other upgrades you suggest IE muffler
( Robert Applebee, 09/01/2015 )Robert,
Yes it will absolutely help with the power on your V10. It is also the most "bang-for-your-buck" upgrade you can do on it. I would definitely start there before doing any other upgrades.
National Sea Breeze 2005, on a 2004 F53 Duraframe chassis, F53 V-10. Has Banks Trans Command module and cat back Banks exhaust, stock air intake. Will the Ultra Power V10 Custom Programmer work w/o disabling the Banks unit?
( steve, 08/28/2015 )Steve,
Yes we can do it without disconnecting the Banks unit. We would just need to know that information at time of purchase.
