First 6K, 11.0 MPG; last 10.5K (since adding 6" lift, 38x15.50, road armor bumpers and brush guards front and rear, 12K hydro winch, 5th wheels equalling about 1000 lbs. and killing the aerodynamics) average is down to 9.1 MPG and dropping!!! (but speedo is not recalibrated). How much of a difference does having everything recalibrated matter ? Would doing a super charger, headers, exhaust, intake, chip, and gears make a worthwhile difference (3MPG or more) ?
