Description

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.

This range AFM delete does just as it says. Unfortunately I found out about it too late. My 09 Silverado had to have new Pistons and rings at 107k miles. Since I got it back from the dealership I haven't driven it without the range device. The truck runs good, that annoying vibration on highway driving is gone, and hopefully there will be no more oil consumption. I only checked one tank and I went from an avg if 15mpg to 14.6 I would recommend this product!

Awesome Product

I have been using the Range AFM Disabler in my 2014 Corvette for the last few weeks and simply love it. It works perfectly, absolutely no issues. Unit firmware is the latest Version7. Super fast shipping from AutoAnything.

This is a great little device. It does exactly what it is supposed to do. My 2008 5.3L Sierra 4x4 has been using about 1qt of oil every 1000 miles since about 45,000 miles. The truck now has about 73,000 miles. I've been adding Rislone engine treatment with each oil change ever since discovering the oil issue to help prevent the control rings from sticking due to the oil burnoff. Well, I can tell you that I've driven about 600 miles since plugging in the Range device and have not lost one drop of oil yet. And as an added bonus, I find the transmission downshifts a whole lot smoother. There is also no more V-4 to V-8 power lag(instant power) and the fuel mileage has not really changed. The driving experience has been greatly improved in my opinion, feel like I have a new truck again. I'm waiting for summer blend gas to hit the stations to see what kind of mileage I'll get.
