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.

Before installing the 87 oct tune on my 2014 GMC Sierra, the gas pedal was stiff and the truck had a hard time getting out of its own way. Now it drives as it should have from the factory! More off the line acceleration and torque, plus a noticeable difference while towing my large camper.
