9.5 is my average with a about 13 gal. in the tank, I got 8.98 one time but that was down a slight hill and I've also gotten a finished speed of 91 on a 1/4(forgot the time) but that was down a big hill. Kinda hoping my truck will get woke up more with the custom tune. I do like the settings its at where it has all the properties of the 93 except the timing down for 87 and all the shift points lowered, get great mileage then I can hammer down, but still not very quick.
