DFM Pro Silverado 1500 23+

Designed to disable Dynamic Fuel Management (DFM) and Engine Start/Stop to keep your engine running on all 8-cylinders all the time, the DFM Pro restores the consistent power, performance, and exhaust tone your truck or SUV was built for. By preventing unwanted cylinder deactivation, it eliminates the lag, vibration, and inconsistent throttle response commonly caused by GM’s factory fuel management systems. New for the DFM Pro is built-in pedal booster control, allowing you to adjust throttle sensitivity on the fly directly from the app. Fine-tune your driving feel in seconds, whether you want smoother daily driving response or a more aggressive throttle curve for towing and spirited driving. No wiring. No separate control module. No dash-mounted hardware. The smartphone app also allows the ability to read and clear Diagnostic Trouble Codes (DTC's), check your vehicles Emissions Readiness Monitors and even Re-Activate DFM at the touch of a button should you ever want to. Installation remains simple and completely plug-and-play. Just connect the DFM Pro at the ECM and go. No tuning, tools, or permanent modifications required. It can be removed at any time to return your vehicle to stock operation.

• Some applications may still encounter 0-Cylinder Mode (Decel Fuel Cutoff) 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 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
