Just back from syr. bought some 100 octane unleaded race gas, relatively cheap,that will get me through the end of the driving season. Will use the mix to store the car.
As to the tuning it was done in detroit, so it probably won't go back there. I have a guage, but the guy I bought it from doubted it worked right. How do you know what setup you have? I believe you when you say if it doesn't work right, it could be bad. Even with an accurate guage wouldn't it be too late if you were really on the supercharger? Seems it couldn't react fast enough.
Over the winter I'll figure out the tuning question, and get educated on how all this stuff works. Thanks everyone for the help.
