MotorOps HP Tuners 2017- 2019 Duramax L5P Single Tune

This was my second order and 2nd truck to delete. Tunes are great and both trucks run well. Will be doing more business with y’all!

Top notch customer service

Always a pleasure working with these guys.

L5P optimized stock tune

The tuning is spot on and the truck runs flawlessly. My only complaint is the egr kit is a cheap kit, I had leaks from the supplied coolant/oil turbo gaskets and the cap supplied for the turbo coolant return line was the wrong size and very thin. Once I replaced the gaskets with oem gm ones and bought an additional silicone cap everything was good to go.
