I was getting 22 on a reg basis for a while, now I average 18-19. I was averaging 17-18 with the lift and big tires, and I sure dont drive mine easy.

i doubt it. someone here didnt post up their mileage.

the best i have gotten is 18mpg and that was doin 60mph on the interstate following a big-azzed U-haul so I wasnt even breaking the wind, I was drafting him.

mods are superchips, smaller tires, 3.42 gears and catback

4.8/auto truck also
