Unleash the full power of your GM V8 engine with the all-new DFM Pro, engineered specifically for 2021–2026 GM SUVs and 2022.5–2026 GM 1500 trucks. Building on the proven performance of our original DFM Module, the DFM Pro now features integrated Bluetooth connectivity and full smartphone app control, giving you total command of your driving experience right from your fingertips. 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. Whether you’re towing, daily driving, or simply want your V8 to stay a V8, the Range Technology DFM Pro ensures your vehicle delivers smooth, responsive power every time you hit the gas. Compatible with late-model Chevrolet Silverado 1500, GMC Sierra 1500, Tahoe, Suburban, Yukon, and Escalade models, this next-generation device gives drivers unmatched control over their vehicle’s performance. Manufactured and tested in the USA, the DFM Pro provides safe, reliable performance without altering your factory tune or voiding your warranty. Experience the difference of running all eight cylinders, all the time, with the added power of Bluetooth control. Better acceleration, enhanced exhaust tone, and customizable throttle response all in one advanced, wire-free solution.
