Hey all. Just put in a Borla exhaust system under my S2k ,2003, and have the AEM CAI coming Friday. Since the are no chips or programers for our cars yet I was woundering where to go next? Any ideas? Anyone here with an after market ECU? Would love to here some ideas.

Thanks,
Paul

 

get a vafc, its an ecu piggy back

 

How about a header?

 

4.77 gears,the best bang for the buck!

 

if you're not going FI, gears will definitely give you some real power. well, not REAL power. more theoritical power, but power nonetheless.
