After my engine/trans mods, and my 35 inch tires, 11.2 is the best iv seen. That's 55 mph with the cruise set. Anything outside that, mileage goes down.
That is terrible, did you get a tune and adjust for tire size? even with 35's you should be at stock MPG numbers or better.
With a cam and a correct tune and fresh rebuilt trans and a corrected speedo he could be at stock numbersI really doubt anyone get's stock mpg after going to 35's...
