Will the tuning affect emissions testing as required by the state of Arizona? Does towing a vehicle figure in determining the tuning specifications? ( Rick, 04/05/2021 )

We do not have certifications with any state for emissions testing, we recommend returning the vehicle back to stock before taking it in for testing. With an RV already being under load all the time, we don't really need to take towing weight into consideration as we are already setting them up for max GCWR.

2011 Winnebago 32’ on E450 chassis with the v10. If I put the tuner on it, then decide to do the K&N, is there a different tune for this? Should I do it all at once? Not really having problems with power, just shifting from 4th to 2nd and landing on the dashboard when there is little or no incline. Thank you. ( Jim , 04/04/2021 )

Yes, we would tune the engine differently for the addition of the cold air intake. If you were to add this later on, we do not charge anything to update your tune and it can be emailed right to you!

If I be purchase this product for our 2015 Thor challenger Rv and we happen not to see or feel a difference. Is the product available for return ? ( Kevin Fitz, 04/03/2021 )

We 100% stand behind our product, if you are unhappy with the results, we will refund your money.

We own a 2021 Thor Freedom Traveler 27A (standard Triton V10 engine). Speed maxes out at 76mph (uphill, downhill no matter), which is fine 99% of the time, but sometimes when I'm trying to pass this becomes a problem. Will tuning remove the speed cap? ( Dave Keselica, 04/02/2021 )

Yes, we can remove the speed limiter, just leave the note in the order comments to do so.

Hi
I have a 2015 challenger motorhome we travel across the country and I’m looking for better gas mileage and torque and HP to help with hills and cruise control. Will these tunes help for sure ( Kevin fitz, 03/31/2021 )

Yes, it will definitely improve the performance. We can't guarantee a fuel mileage improvement but it won't negatively impact it and most folks do see some sort of increase.
