The GM E90/T93 Upgrade Kit gives you the ability to upgrade 2019–2022 GM E90 ECMs and T93 TCMs without removing a single controller from the vehicle. This is a true DIY solution for shops and builders who want full tuning capability without downtime or mail-in delays. Each controller uses its own dedicated cable, so you only upgrade what you need—no forced pairing or unnecessary steps.

The E90 ECM is used in 2019–2022 Chevrolet Silverado and GMC Sierra 1500 models equipped with the L84 or L87 V8 engines. The T93 TCM is found across a wide range of GM platforms, including 2019–2022 half-ton gas trucks, 3.0L Duramax models, 2020+ Camaro applications, and 2020–2023 Silverado and Sierra HD trucks running the 10-speed automatic.
