Why Delete AFM?
AFM is designed to improve fuel efficiency by deactivating cylinders when full power isn’t needed. While this sounds great in theory, many vehicle owners have experienced lifters collapsing, excessive oil consumption, and overall reduced engine longevity due to this system. Removing AFM eliminates these potential headaches and ensures your engine runs smoothly at all times.Benefits of an AFM-Deleted 4.3L EcoTec3 LV3 Engine
