HELP!!! Supercharger Driveability Problems?
 

Finally finished my supercharger install and my car has some tuning problems. It idles a little erratic sometimes and when I am driving sometimes it will bog between a shift for about two seconds then come back to life. It also likes to die when I am sitting at idle, rev it up to about three, I let it idle again then try to give it a little gas and it just dies.... Can anybody give me some tuning tips, timing, tps, fuel pressure, etc.....

Give this part a try: http://www.windsor-fox.com/spacer_plate.htm

1)plugs should be at least one heat range cooler and gapped to .035

2)(Get a fuel pressure gauge)Base fuel pressure should be near stock,thats like 40psi,but it should go up to around 70-75 under full boost.

3)Use at least 91,92 octane gas

I had this problem with mine for awhile.What I did was first disconnected the battery,left it disconnected for 30 min.While it was disconnected,I cleaned the throttle body out with throttle body cleaner.I hooked the battery back up and drove the car outta town and it was fine.
