Ok guys here is the deal i got 3 g's to spend and i was wondering what i should do first... I already got AEM intake and Apexi WS2 exhaust on my 06 si... I just really want to get the most gains as possible for 3 grand... I went into my local race store and they said i should do my cams, retainers, value springs and a reflash all for like 2300 (all Go-Power). But i really want to supercharge it but i dont know what brand is better either... The Jrsc or the CT??? What kind of gains could i possible see out of those two?? Thanks guys for helping me out...
