Ok so i got an 04 f150 XLT 5.4 4x4...it has a 2.5" leveling kit and a set of 35 at's on 17x9 AE wheels...my question is why in the hell do i only get 225 miles on a full tank of gas...O i forgot to add that it does have a shacker intake with a K&N filter and a flowmaster with a turndown but that should actually help with the backpressure and increase fuel mileage even if its only by a mile...what is the deal can anybody tell me...Or is anybody else experiencing this?

 

Just curious what rear end do you have and a you using a tuner to adjust your tire size.

 

the rear end sucks i dont know what it is but i do know its not a positrack...i dont have any performance device to change anything im not sure what to really get
