What kind of gas mileage gains have you guys gotten with tuners? $3.89/gallon today...went up .20 in like 3 days. this is getting f%&*ing stupid especailly with how much driving i do between school and work.
Well I got a lift and 35s with the stock 3.55s and it stayed mainly the same, but highway mileage went up alot. Imo that is alot!
i have seen about a 2-3 mpg gain and that was going from a 31 to a 33 inch tire and edge evo at the same time i put tires on. so yeah it helps
