I did all that stuff. It wasnt one tank of gas. It was goin on for a while. about the last three months. Its not that I just filled up and went wow the mileage changed! I haven't changed any settings, and my tire pressure is correct and my habits are the same. Thats why i watched it over a period of time. Why I said average m.p.g.'s .It was noticed after using the 87 custom tune for a while. A difference in how it performed. AND THE M.P.G i n 87 mode and then the change to 87 tow.There were no real variables. The only thing I did was change the program.
Thats why I asked the question. Can it be the program?
