The DFM Pro is engineered for 2021-2026 GM SUVs and 2022.5-2026 GM 1500 trucks with the 5.3L and 6.2L V8. It disables Dynamic Fuel Management and Engine Start/Stop to keep your engine on all eight cylinders, restoring consistent power and exhaust tone. New Bluetooth smartphone app control adds an adjustable pedal booster, lets you read and clear trouble codes, check emissions readiness and even re-activate DFM at the touch of a button. Installation is plug-and-play at the ECM, with no tuning or permanent modifications, and removing it returns the vehicle to stock.
