I have an 01 F250 CC SB 7.3 with 46000 miles. I got 4" mbrp turbo back exhaut, K&N filter, Superchip programmer,Auto lite gauges.
Does anyone have an idea why my mileage is so poor? I average around town about 12.8 and hwy pulling about 3000 lbs i'm luck to see 11.2. I've Had it into the dealer and they have told me there is nothing wrong with, But everyone I have talked to told me that there is. I have tryed all different driving styles and nothing seem to work. Please help
