Range Active Fuel Management Disable Device Reviews


Maintenance Man

Reviewed By Eugene H (GREEN BAY, WI) Reviewed for a 2007 GMC Envoy —11/11/2015 6:24 PM

My 2007 Envoy was using about a quart of oil every one thousand miles if a majority of those miles was highway it seemed to use even more oil. I have put on about 700 miles after installing the chip and the dipstick reading shows no oil use so far. Also noticed the rpms at highway speeds run about 200 lower than with the active fuel management putting engine down to 4 cylinders. Noticeable power increase and computer miles per gallon readings have gone up a little.

TruXP Xtune Performance Tuner Reviews


works great

Reviewed By jim f (PHILPOT, KY) Reviewed for a 2010 GMC Sierra —1/27/2016 9:54 AM

Purchased this to get rid of AFM. It was on sale and about the same price as the thing that just plugs into the port to just get rid of AFM. The Xtune can disable AFM along with most features of more expensive tuners. The mileage tune was installed and couldn't be happier with the results. I would recommend this tuner.
