To prevent damage you are going to want to stick with the tune from Kenne Bell. I think fuel pressure and boost guages are a must, you can monitor you boost levels and fuel pressure, then if something looks fishy, you can hopefully catch it before it does any real damage. To make the most power out of the supercharger, you would want to lean it out, run higher octane, and more boost. Safe and most power don't go together. I just installed my KB 6psi last weekend and the pull is amazing, but I have a 01 GT and the higher compression heads are killing me. KC@KB is going to let me know what to expect from the dyno next Monday, I was expecting around 350rwhp, but I think I am expecting too much.
