Key Features
DFM Module for Refresh V8 models - 2021-2024 GM SUV and 2022.5-2025 GM 1500 Truck
- Disables Dynamic Fuel Management (DFM) and Engine Auto Start/Stop systems
- Smart inline technology integrates seamlessly with the ECM
- Allows a true ËReturn to Stock„ status when removed with no trace for worry free dealer services
- All-time V8 mode means better power on demand, a more consistent driving experience, reduced engine and valvetrain wear, and improved long term engine reliability
- Enjoy that V8 rumble and avoid unpleasant exhaust notes and drone from running in cylinder deactivation mode
- Plug-and-play installation can be completed in minutes
- 49-State Emissions Compliant, 50-State CARB EO Pending
- First to market product for Global B and Refresh model support
- To confirm your 2022 model truck is compatible with this unit, check your VIN. The 12th digit in a Refresh model must be a '5' or higher
- This device is compatible with ALL 2023-2025 truck and 2021-2024 SUV models with the 5.3L and 6.2L engine
- Some applications may still encounter 0-Cylinder Mode while coasting when 0% throttle input is detected at the ECM
- We do not control the in-cab Auto Start/Stop switch on the dash, so it will still iluminate on/off with the button being pressed as it factory, even though the system is always disabled with our module installed at the ECM.
- Made in USA
