GM E90 PCM Unlock Service

2019–2022 Silverado & Sierra 5.3L / 6.2L (Non-Global B)

Five Bar Motorsports offers a professional E90 PCM unlock service for 2019–2022 GM trucks equipped with the 5.3L or 6.2L engines that are NOT Global B architecture. Unlocking the factory PCM allows full calibration access so the vehicle can be properly tuned for performance modifications such as camshafts, headers, intake upgrades, forced induction, and more.

From the factory, these PCMs are locked and cannot be modified through standard tuning software. Our unlock service allows the ECU to be fully accessible so custom tuning can be performed.
