I think the head work and headers have altered it enough where I need another tune, because the MAP signal is much higher, which results in dumping more fuel. I'm going to try to correct this myself with a piggyback fuel controller, I'll keep you posted

The ASP kit is nice because it retains factory belt. The pulleys I made produce a 24% overdrive on the supercharger, and it took me nearly a month to track down a belt that would fit it. The other nice thing about ASP is it requires no tune, it works with factory ECU settings.
