Description
Take your 2020–2023 GM 2500HD or 3500HD 6.6L gas truck to the next level with the Edge Evolution CTS3 85453-K. Built for L8T-powered Silverado and Sierra HD trucks, this all-in-one performance tuner features in-vehicle ECM unlocking, preloaded performance tunes, transmission shift strategies, throttle sensitivity adjustment, and real-time monitoring with a brilliant full-color touchscreen.
Using the included Locksmith module and ECM unlock harness, this tuner unlocks the ECM directly through the OBDII port—no ECM removal required.
