GM’s Active Fuel Management is a solid idea.

Because it turns off half of your V8 engine’s cylinders under light load conditions, it can improve the fuel economy of your vehicle. But what if you don’t care about fuel economy? Or what if you’d rather have your vehicle operating on all eight cylinders for maximum power?

That’s where Range Technology comes in.

The Range AFM disabler plugs into your OBD-II port and essentially eliminates the Active Fuel Management function. It’ll keep your GM vehicle in eight-cylinder mode all the time—no more dropping cylinders! That makes it ideal for trucks or SUVs that see off-road time or get tasked with hauling heavy loads. And the device is the only one of its kind that works without reprogramming your factory ECU.

Also known as an AFM delete programmer, this device works on all AFM-equipped GM vehicles.

NOTE: Some parts are not legal for use in California or other states with similar laws/regulations.
