⚡ Keep your GM roaring in full V8 mode—because half power is so last season!
The Active Fuel Management Disabler Device is a compact, plug-and-play solution designed for GM V6 and V8 vehicles. It disables the AFM/DFM system to maintain full cylinder operation, enhancing engine power and eliminating cylinder drop without altering the ECU. Compatible with most GM models except 2019+ Silverado and Sierra with specific engines, this device ensures a smoother, more powerful driving experience while requiring minimal user intervention.
