Damn I'm jealous! My MPG sucks ass. I checked manually...13.7 average MPG, that includes partial highway and city. Last I checked highway, it was about 70-75 mph, 6th gear. I was struggling to maintain 18 mpg. That's down from 23 before.
Wait a second, do you have a TVS, or just a new pulley and tune on your stock supercharger? I have a TVS, which Jon Lund said could have more parasitic loss.
