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.

Great results

Reviewed By Jason B (Flowood, MS) Reviewed for a 2014 GMC Sierra —2/21/2017 8:11 PM

I used the tuner to adjust my speedometer for larger tires I put on my truck. That plus the fuel saving setting increased my mpg by almost 20%. I haven't had time to play around with the other settings yet. It's very easy to use. The whole process including reading instructions took about 10 mins.
