Have your TCM flashed by us in-house. No charges for credits or unlock.
Optimize shift points, line pressure, converter lockup, increase efficiency, and utilize adaptive shifting.
This is not an unlocked HP Tuners TCM.
The new tunes work great and have a lot longer shift points when pulling my trailer. Fast shipping too!
After a couple weeks running the truck with the tcm tuning I feel like the truck shifts a lot better, it’s smooth and quick. I can also feel the truck has some more torque. I love it
Truck runs and shifts wayyyy better now with the ppei tcm. Definitely worth the money and super super easy to install.
