When it comes to horsepower, dropping cylinders is a recipe for flat-lined performance. This especially holds true with Active Fuel Management (AFM) systems installed on V8-powered rides and rigs. While they're great for saving you at the pump, turning a V8 monster into a wheezing 4-banger understandably kills performance. Wake up all 8 of those potent pistons for full-time power with the Range Technologies Active Fuel Management Disable Device.
If Active Fuel Management has a stranglehold on your ride, the Range Technologies Active Fuel Management Disable Device is the answer. This powerful module completely disables AFM, allowing your ride to run on 8 cylinders constantly. All it takes is a few seconds to locate the diagnostic port in your ride and plug in the Range Technologies Active Fuel Management Disable Device. This results in a more responsive ride with all 8-cylinders available full-time and ready for action.
No adjustments are needed to enjoy the full performance of the Range Technologies Active Fuel Management Disable Device. And all changes are fully reversible, so if you need to restore the stock Active Fuel Management program, simply turn off the engine and unplug the device. Say goodbye to unpredictable power and snail-like acceleration with a Range Technologies Active Fuel Management Disable Device. Best of all, Range backs their Disable Device with a 1-year warranty.
- The Range Active Fuel Management Disable Device cannot be used in conjunction with aftermarket tuners that need to remain attached to the diagnostic port.
- The Range AFM Disable Device is NOT a programmer and does NOT change the ECU's mapping or memory locations. It is a dynamic interactive device that actually participates on the vehicle's communication line (bus) and revises the way the ECU uses its STOCK calibration to lock it in V8 mode. Since the Range AFM Disable Device does not change the factory programming in any way, your vehicle will still comply with the factory certified emissions profile.

I can't believe the difference it made. You can really tell in 3rd and 4th gear when AFM wants to kick in. All the power stays in it, even passing power. This thing, plus exhaust, plugs, and CAI made the Tahoe a BEAST!!

Shipping was fast, just plug and play. Mileage went up, does what it was designed for. Great product, a little pricey

Purchased my 2017 GMC Sierra just a few weeks ago, saleslady didn't tell me anything about the truck going into V4 mode. After noticing power drops and almost getting hit waiting on it to switch out of the V4 mode, I had to read the manual. Educated myself and hated the V4 mode! Found this unit while browsing on the internet and purchased here at autoanything.com. This unit has allowed me to fall in love with my GMC Sierra. What a difference!

I read reviews before I purchased this device. Some said it would drain the battery. I left my truck for several days with no problem. So far, it works great, recommend for sure. Autoanything A+ as well
