Blue Light Special

Reviewed By James P (Coweta, OK) Reviewed for a 2007 Pontiac Grand Prix —3/23/2015 6:34 AM

Installed in a 2007 Pontiac Grand Prix GXP daily driver. I have driven for a little over two weeks, 750 miles and two tanks of gas. So far so good. The Range AFMDD performs as advertised. No more stuttering and stammering of the AFM and collapsing lifters. I don't usually drive the car on weekends. No noticeable battery discharge. Gas mileage has not changed much. Maybe 3/10ths of a mile per gallon. I expect the oil consumption to virtually stop as well. Time will tell.

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.
