Or, @75 mph speedo, actual speed is 77.8 mph

Must by my speedo is off the difference, which makes the MPG worse yet...

i have a 05 f350 cclb srw w/3.73 grs and stock size cooper atr's @ 65psi.the only mod done soo far was a 4" turbo back exhaust. best mileage with new ficm has been 17.8 highway running cruise @ 75mph, average around town 14-15. also mileage seems to depend on what brand of fuel i fill up with. so far marathon and sunoco have brought me the best economy.
