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.

Range was founded in 2010 by electronics engineers looking to provide simple to use solutions to Active Fuel Management systems found in GM cars and trucks. The goal was to offer inexpensive products that would not re-flash the factory ECU. After hundreds of hours and thousands of miles testing, Range Technology is an industry leader and has expanded to offering multiple Active Fuel Management, Multi Displacement System and Auto Start/Stop products for late model GM, Chrysler, and Ford applications.
