The Range AFM/DFM Disabler allows your V6 or V8 GM vehicle to run in full cylinder mode at all times, preventing the Active and Dynamic Fuel Management systems from dropping cylinders. Our patented technology is the only product that will disable Active or Dynamic Fuel Management without reprogramming the factory ECU. Full power delivery all the time without factory warranty concerns.

Has the Active Fuel Management system in your V6 or V8-powered GM car been slowing you down? Are you tired of the annoying shuddering of your engine and the drone it produces from constantly activating and deactivating cylinders? Meet Range Technology's answer: the AFM Disabler. Our module is plug-and-play and reverts your vehicle back to stock when removed. Because no tuning is involved with your vehicle's computer, this product will not void the factory warranty. Not only does the AFM Disabler keep your vehicle running smoothly, but it will also have you running on all cylinders, all the time.
