Good so far

2018 mega cab dually towing my toy hauler 20k when i move jobs and otherwise unloaded on the daily. Trans feels good after 1700 miles and seems to be getting more responsive each day. No shift flare outs no hard downshifts. Engine tuning is through another company right now, but that will change soon. Currently stock fueling with cai. Future includes banks boost tubes intercooler and intake horn. 18.3mpg currently running 120hp daily with a light foot

2018 Ram Mega Cab AISIN

Guys I'm not even kidding you when I say that I almost sold my truck because of that damn AISIN tranny, The shifting the de fulling is some of the worst in history, these folks at PPEI saved me from selling my truck. If you own an AISIN you MUST get this tune This will put a smile back on your face.

Big difference in shifting, more responsive and seems to stay in the meat of the power.

AiSiN trans tuning

Overall the shifting improved after putting about 300 miles on the truck, ultimately still need some adjusting on the tune the 1-2 , 2-3 , and 3-4 shifts are still very strung out, and maybe change up the converter lock up some also.

Had the tune installed today and a total different truck for the better! Going to haul cattle next week and see how it performs.
