I have a 2004 Excursion with the 6.0. I have a bully dog 4" exhaust, bully dog air intake and the Edge Evolution. I keep the evolution on economy but sill not getting the mileage I think I should be getting. The EX is on 33's with a level kit. What kind of mileage should I expect with this set up? Any information on this would be great.
