Recently bought an 07 Si and I don't know if I want to stay naturally aspirated or look at a supercharger. I was wondering if anyone has comments on the reflash for my engine. any input appreciated.

 

i read somewhere that as of now there is not ECU upgrades for that generation of civics. there was some one asking about it on clubrsx.com and they said there was no way to "tamper" with the ECU. soooo you may be better off to do bolt ons and supercharge it later. also, your going to want to do an Intake/Header/Exhaust either way you go.
