PRODUCT DETAIL

Key Features & Description

The Range Technology RA003B AFM/DFM Disabler-Blue is a plug-and-play OBD-II module for 2007-2022 GM Silverado and Sierra 1500 trucks with gas V6 and V8 engines. It disables Active Fuel Management (AFM) and Dynamic Fuel Management (DFM) so the engine stays in full-cylinder mode, and it also disables the factory Auto Start/Stop. It does not reprogram the factory ECU, and it returns the truck to stock when unplugged.
