POWER THAT PERFORMS

Great!

I found PPEI by their great reputation in the industry. After dealing with these guys, now I know how they received their reputation!
I was always able to speak to a knowledgeable enthusiastic person on the phone. I appreciated the ability to talk to somebody over the phone and not just via email. They were very willing to answer all my questions.
I purchased the PPEI Aisin tuning package for my 2020 Ram 3500 diesel HO. After installing, I just sat back and SMILED. Trans shifts smooth with good acceleration between gears.

Tunes really solidified my transmission shifts. Staff was very helpful. Overall process was super easy.

This tuning package is very straightforward and simple to install. My truck had a Super-chips tuner on it when I bought it and the truck never really felt like it ran “correctly”. These tunes really did transform the way my truck drives, it’s so responsive and fun to drive now. Happy to be apart of the PPEI tuned community!

Correct part, shipped fast and a good price always easy buying from PPEI

Awesome change in shifting. Very smooth. Well worth the money. You won’t be disappointe

This is the best upgrade you can do to your Aisin Transmission!!

100% will get all further tuning needs from PPEI.

Background: 2020 L5P, GDP ECM tune & 5inch full exhaust. 35inch tires. Tune level 4 for Daily driving & Level 1 for towing.

It’s been 3k miles since I have flashed TCM Tuning by PPEI and I love it!
Instantly , you’ll noticed shift points changed for the better. I drove normally for about 1k miles so the TCM adaptive learning to could learn my style of driving. Once 1k miles break in was completed, I did do a couple of 75-100% throttle pulls and it is night and day from stock. (Break-in not required by PPEI, but personal preference).
During towing, I did enjoying the higher shift points while driving through the mountains. I did notice downshifting happens more quicker. At times, if the transmission temp is under 100F, there is a slight weird shift between 2-3, like a clutch slip feeling. Happens at 10-25% throttle but won’t do it again once the transmission is warmed up. Overall, I am happy with the end results.

I purchased PPEI Asian Tuning go my 2019 Ram 3500 Dually HO during there Memorial Holiday sale at 20% off which was a great deal. I drove my truck in town for a few days and was really expressed with the shift timing and firmness of the shifts. This weekend was my first test drive while towing my 39’ Momentum toy hauler into Northern NM thru Bobcat pass 8,300 ft pass and into Cimmerian Canyon. The temperature leaving Albuquerque was 96 degrees my transmission temperature stayed 156-161 degrees the entire trip up north. I did have to rely on customer support a bit due to being unfamiliar with the update process for EFI Live Auto Cal. After I got the unlink code the PPEI instructions were very detailed and easy to fallow. I direct messaged my buddy for his “Eddie’s Life “ honest opinion. I am still relearning my driving habits but loving every mile in my new transmission tuning. The firmness of the shifts is great and works well with my ATS thermo bypass valve. This was my first experience with PPEI tuning and I would definitely be on the radar for future tuning upgrades. This is a real deal at 25% off

PPEI's Aisin tune is subtle, yet makes a big difference. That may seem like I'm contradicting myself, but the tune improves the drivability of the Aisin without any drama, smooth and seamless. Previously, I was using the manual gear lockout buttons on the steering wheel just to keep the truck in fifth gear instead of 6th at 35-45mph. No more! Seems to improve the exhaust brake functionality as well. Very pleased.

I dont know Kory personally but I know his products are always top notch and backed by tons of R&D and countless hours of fine tuning. I dont regret buying trans tuning for my 22 3500 HO definitely runs a lot smoother shifts. Deleted truck runs great. Took some time getting used to the longer shifts but it really woke the truck up! Keep up the great work guys!

Had this truck give us some problems getting it straightened out, but Ryan and Zach both were working with us the entire time to straighten it out. Great tunes and even better customer service.

When I originally tuned my truck i went with a different company. The truck never ran good, had 0 boost in 5th gear and downshifted a bunch. So I ordered Ppei tunes and trans reprogram and with the help of Ryan got them loaded onto the truck. Truck runs 100% better and pulls like it should now. Thanks a million guys.

Great customer service
