WHAT ELSE CAN I DO?.................

Turn your cap locks off :thumbsup:

I've read that you can't gain a whole lot of power by changing pulleys unless you also add an intercooler or run racing gasoline, since the more boost you run, the hotter the intake charge gets, and the more the engine has to retard your spark timing to prevent knocking. Don't have any direct experience, though.

Some intercooler links:

Warning--because the intercooler has to fit between the supercharger and the intake manifold, it has to be an air-to-water intercooler since an air-to-air intercooler would be too big. Air to water intercoolers are EXPENSIVE, unfortunately...

You can also get a performance computer chip that will raise shift points and such, but I don't know how much real gain you'd see, and whether that'd be worth the expense.

Thanks for your help................
