2019-2022 3.0 LM2 Duramax Truck EZ Lynk Custom Performance ECM Tuning

Get your 2019-2022* LM2 tuning for the Silverado or Sierra 1500 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 Duramaxtuner has honed over years of tuning different Duramax platforms to maximize reliability and longevity of the powertrain. 

Calibrated Power 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 (available separately) 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. 

*NOTE: Not Compatible with 2022.5 models equipped with the LZ0 3.0L
