Haha, I get 20-22 highway mpg with 4.10s
Drag racing... I see MAYBE 6mpg, and that's mostly on the return lane!
My 03 Cobra got 23 mpg at cruising speeds with 4.10's with 500 at the tire.

So, when I said I get two mph better at 80 mph than you, you think my gear ratio is wrong? :lol:
Mines been sitting for a few months without oil. It's getting great mileage. Haven't spent a dime on gas in a while :dw:Must be the Mobil 1 ;-)
Retune your car, before you upload the tune, make sure axle ratio and rev per mile are accurate.
285/40/18 & 285/35/19 both are ~770 revs per mile.
What gears are in your car?
Do you use gas that is up to 10% ethanol?
Not sure what the gas has to do with it unless ethanol increases mileage I htink is highly unlikely.
Same as oil. 5W is about as thin as it gets.
I do not use cruise control on hilly roads. I lift before I crest a hill and I coast most of the downhill side. I rarely pull any boost and try to pull vacuum as much as I can when I drive.
