I've put a couple of tanks of gas through my SC now. I only drive it to work, and it's all back roads with a couple of stop signs. No real stop n' go city driving.
I'm averaging about 16mpg. This seems horrible to me for a bone stock car.
Any suggestions on problems to check for? I've noticed it only makes about 9lbs of boost, so perhaps a vacuum leak? The ignition system seems to be in decent shape - good idle and no misses. No bogging or signs of a fuel problem either.
