Summary

    Description

    Get your 2020-2021 LM2 tuning from the experts. With the option to choose between 2 custom tunes designed to bring out the best in both top-end power and towing torque for the 3.0L Duramax. These tunes will improve the drivability and performance of your 3.0L Duramax using the same tuning methods we’ve honed over years of tuning the L5P to maximize reliability and longevity of the powertrain. 

    Our custom tuning is exactly what the LM2 needs to wake it up and unlock its true performance potential. Combining the engine tuning with T93 Transmission tuning is the ultimate way to match your transmission holding capacity, shift schedule, and torque converter clutch engagement to the new found torque of your 3.0L Duramax allowing it to lug like a diesel. LM2 ECM Unlock Service, ECM Tune, Hardware, and Credits included.
