Well I have a 2006 6.0 with a powermax and sct tunes xtreme street by innovative and a 4 inch exhaust. I cant figure out my stinking Fuel millage situation!! I got 11.1 mpg drove 246 miles 156 being highway the rest short drives 2 miles each way which I know isnt gna help

does that seem low I drove probably 242 miles without going over 2000 rpm and prob 4 giving her hell I took my buddy for a ride who just put a supercharger on an 04 f150 but I just dont think 11.1 mpgs is right?

Thanks guys
