Will your unit adjust the transmission shift points? Would like to hold in a higher gear / lower rpm while pulling long hills. ( Andre , 07/02/2022 )

Hello Andre , the UPFORD tuner will greatly reduce the annoying downshifts, that is one of the most noticeable features of the tuning. The increased power allows the transmission to hold the gears longer , which helps fuel economy as well as makes merging onto the freeway easier and safer .

Will this tuner work for a 2022 ford e450? ( Michael, 06/03/2022 )

Yes, we are currently offering the new V8 tuning on a limited basis. We are not currently able to pre-load your custom tune so it will require you to have a Windows PC so that we can email the tune file once you retrieve us some vehicle info with the device.

Not sure what chassis this I have, but MH is 18 holiday rambler (RENO) coach with a V-10. Will your device marry to this coach? If so, which one? ( Derek Goins, 05/25/2022 )

Hello Derek, you have an F53 Chassis with a 16, 000 GVWR , The UPFORD tuner would be the correct product for that vehicle and it will marry to it, it can be returned to stock ( unmarried) and the device can be updated with a new tune if you were to sell the RV and get another Ford .
