if u supercharge how much does your precious gas milage drop
After you get over the fun factor mine went up not down. I don't need to down shift into 4th for passing now I just squeeze the throttle in 5th. I still run 3.08 gears so my RPM is still in check. If you tune the car correctly and not run a FMU you will keep your fuel mileage.
I went from 27-28 mpg on interstate trips to 20. But I have a conservative tune. Throwing a bit of extra fuel at it to avoid detonation.
