The Range Technology AFM/DFM Disabler for GM vehicles is the perfect solution for drivers who want full control over their engine’s performance. This simple plug-and-play device disables GM’s Active Fuel Management (AFM) and Dynamic Fuel Management (DFM) systems, allowing your engine to run in full cylinder mode at all times. No more frustrating transitions between V4 and V8 operation. Just smooth, consistent power whenever you need it. Designed for GM trucks, SUVs, and cars, the AFM/DFM Disabler helps eliminate issues like excessive oil consumption, lifter failure, and rough idle, giving you improved reliability and a stronger, more responsive driving experience. Installation couldn’t be easier, simply plug the Range device into your vehicle’s OBD-II port, and it instantly disables cylinder deactivation without requiring any tools or permanent modifications. It doesn’t reprogram your ECU or leave a trace; just unplug it at any time to return your vehicle to stock operation. The disabler is completely safe for your GM’s electronics and features built-in power management to prevent battery drain when the vehicle is off. Whether you’re towing, off-roading, or daily driving, the Range Technology AFM/DFM Disabler ensures your engine stays in full power mode for better throttle response, smoother acceleration, and improved performance consistency. Compatible with a wide range of GM applications including the Chevrolet Silverado, Tahoe, Suburban, GMC Sierra, Yukon, and Cadillac Escalade. This device is trusted by enthusiasts who demand the best from their trucks.
