20-22 Duramax LM2 Tuning Ez Lynk

This product does not require any prior unlocking of the ECM as the EZlynk will perform this during the tune flash

Unlock the full potential of your 2020-2022 GM Sierra or Silverado 1500 equipped with the 3.0L LM2 Duramax engine with our custom tuning package. 

Designed to enhance performance, improve drivability, and maintain reliability, this tuning solution offers three distinct power levels tailored to your driving needs.

This product is for the pickup only, all of the SUV 3.0's are E66 ECM which is a different product option and not currently available on EZlynk at this time. 

This product is for NON-REFRESH Trucks Only!! An Easy way to tell if the truck is a 20-22 or a 22.5 refresh is the center radio display. If it has the large new display then it is a 22.5+ truck and the E66 controller.
