Old swans truck completely runs on propane no gas. Do your tuners work for propane systems. ( Jeff, 10/12/2021 )

Hello Jeff, Unfortunately our tune only works on gasoline powered engines .

I live in California, where RV must be smog tested every 2 years. Your ECM has your decal on it and it looks a little different from stock ECM, which will draw attention to it during smog inspection. What is the fee to set MY computer to your parameters, so it will still look stock? ( DONALD MADDEN, 07/20/2021 )

We can't ship this product into California due to CARB regulations. The sticker does not have to be on the module, though.

Do you sell an OBD2 scanner for the Kodiak? ( Nicole, 07/19/2021 )

We recommend the ScanGauge2: https://www.ultrarvproducts.com/SG2-ScanGaugeII-OBD2-Vehicle-Monitor

2005 Tiffin with 8.1 Chevy. Do I need to change both TCM and ECM ( Michael Bourque, 07/06/2021 )

You do not need to change the TCM , it is an option to further optimize the shift points , as well as lowering the speed to shift into overdrive under light throttle and further reduce downshifting.

I have a 2006 Fleetwood Southwind. Do I need just the ECM? If so, what is the cost? ( Mark E Conant, 06/23/2021 )

Yes, just the ECM for your application. The cost is $595 and if you want to pay for a core exchange, that is an additional $150.
