bad fuel mileage......?
Ive got an 04 2500 six speed cummins and i can hardly get 11 miles to the gallon. 5 in ch exhaust k&n intake. The truck does have a 5 inch lift and 37's. I know that drops the mileage but i didnt think it could drop it that much. I have two programmers a bully dog pup and hypertech. Ive tried them both on the mileage setting and it actually gets worse. Does anyone have any ideas why its so low?
