2019 - 2024 Ram 6.7L Cummins Aisin | Transmission Tuning by PPEI

Great tune for heavy pulling

After deleting my 2022 ram 3500 the truck had less power then it did stock and the guys that programmed ecm did trans tune, with the Aisin transmission it ripped first day then very next morning truck was at 1/2 power. Ppei got the trans back right and my 3500 is back to pulling hills like no other with my 45’ trailer and 30 4x5 round bales on it.

We've made a few customers happy so far, and most definitely will be making more customers happy with this tuning!!! Great work PPEI Team!!!

What an impressive difference

Great communication through the entire process. Tune made a world of difference in how the truck performs. I definitely recommend going with PPEI for an Aisin trans tune.
