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.
Better than expected!
The hypertech max energy programer really worked with my stock 2006 Nissan Pathfinder. I run mid-grade gas in this truck and programed it for low grade gas. Immediately noticed that my gas milage went from 14.8 mpg too 17.6 mpg and I drive over mountainous terrain daily. I also adjusted the speed limiter rpm rev limiter during the tune and the vehicle feels like a new machine with at least 15 more horsepower.
