What kinda milage are y'all seeing with the 3.31 gears leveled and bigger tires ??
What's the city/highway mix and what was your mileage before?I average a little over 15 mpg, 6" lift and 35's
And your speedo will be way off unless you have some correction device.Only issue is without a tune and putting 35's on your truck will accelerate like a slug finding some wet grass at dawn.
No it doesn'tWill a tune void warranty ? Does it leave a foot print ?
