GM Duramax E90/T93 Upgrade Kit (2019-2023)
Type: Tuners
Streamline module access without removing your controllers. This GM E90/T93 Upgrade Kit enables in-vehicle access upgrades for supported ECM and TCM units, eliminating the need to remove the modules from the truck. Designed for efficiency and safety, it reduces installation time while protecting sensitive electronics during the upgrade process.
Built specifically for supported 2019–2022 GM non-Global B platforms, this kit provides a controlled and repeatable procedure for preparing E90 ECM and T93 TCM modules for calibration access. By keeping the controllers mounted in the vehicle, the risk of connector damage, mounting stress, and unnecessary handling is significantly reduced. Ideal for professional tuning facilities and experienced enthusiasts looking for a safer upgrade workflow.
