Blue Light Special

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.

So far so good.

Reviewed By Bruce K (LYNDON STATION, WI) Reviewed for a 2013 Chevy Silverado —5/22/2017 8:28 PM

I just dropped the 87 Octane tune with firm shifts and turned off AFM. The truck shifts smoother and it seems to have helped a lot with the driveline clunk when getting back on the gas after slowing down. A custom tune is in the future.
