Range Range DFM Inline Module 2022-25 GM Refresh RA007

DFM Module for Refresh V8 models - 2021-2024 GM SUV and 2022.5-2025 GM 1500 Truck

By installing the DFM Module, users can effectively override the vehicle's built-in cylinder management system, allowing the engine to run on all cylinders, all the time! This leads to a better driving experience, and better long term engine reliability. 

Features:

• Disables Dynamic Fuel Management (DFM) and Engine Auto Start/Stop systems
• Allows a true ‘Return 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
• 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 2023-2026 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 illuminate on/off with the button being pressed as it factory, even though the system is always disabled with our module installed at the ECM.
• We do recommend removing the DFM Module before performing any GM Over-the-Air updates or visiting the dealer for vehicle updates via OBD-II port
• Made in USA
