Range Technology AFM Disabler | 2005-2020 Chevy/Buick/Cadilllac 3.9L, 5.3L, 6.0L, 6.2L

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

This module is "universal" and will work with GENERAL MOTORS vehicles (trucks, cars, SUVs) with the Active Fuel Management (AFM) system. This includes both V6 and V8 variants.
