I can't wait for the custom tunes. The record the other weekend in my truck was 20.7. Tail wind approx 25 mph. Traveled appox 90 miles on a 2 lane going 55-60 and some passing. The numbers matched on paper! On the way back was at 17 mpg.
Had a tank of 50/50 87-92. Stock tune only
But had tried the canned performance tune when I first got the gryphon and now ever since I went back to stock better mpg's?
