So, I'm supposed to be getting a nice chunk back from taxes this year (not "supercharger" nice but nice none the less). Considering picking up an SCT and 93 tune from VMP but wonder if it's worth it since my Bullitt is bone stock aside from the axle backs and R2C filter on the Ford CAI. I don't plan to throw a supercharger on this car until I've paid it off. The car doesn't spin those 275s like it did the 255s. Would I even notice a difference?
