We provide quality Duramax tuning for Duramax vehicles ranging from the 2001 LB7, all the way to the 2023 L5P. From pre emissions vehicles, to vehicles that have complex systems including EGR, DPF, SCR, and DEF. From a maximum safe horsepower with just tuning of about 400 rwhp to 600 rwhp on the L5P. We have something available for everyone. All RPOs including 2.8L LWN, LB7, LLY, LBZ, LMM, LML and L5P (soon to include the LM2 3L Duramax) have the option of a single power level or switch on the fly tuning. The 01-10 Duramax's (LB7, LLY, LBZ, and LMM) are tuned using EFILive. The 11-16 LML's are tuned using EFILive or Ez Lynk. The 17-23 L5Ps are tuned using HP Tuners. All RPOs have optional Transmission Tuning.

The overall goal of our tunes is very similar across the Duramax, Cummins, and Powerstorke trucks. Improve driveability, increase horsepower and torque, delete dead pedal, and enjoy your ride even more whether it's for work or play!
