aFe Scorcher Blue power module for the 2019-2026 GM 2.7L turbo trucks (Silverado 1500, Sierra 1500, Colorado, Canyon, Cadillac CT4-V). It plugs into the factory engine sensors and raises turbo boost for added power and throttle response, with four settings (Stock, Sport, Sport+, Race) selectable from the in-cabin LED switch or over Bluetooth through the free smartphone app. The app shows boost (MAP/TMAP) gauges, custom-tunes each mode, times 0-60, and leaves no trace on the ECU.
