I just joined this site, and i'm looking for some advice to help me along with my 03 wrx. I've done a couple simple mods and i'm satisfied but i have that addiction to keep on adding, like i'm sure that all you have. So far i have HKS: Carbon Ti Exhaust, up-pipe, down pipe, and bov. Rota wheels that i don't plan on keeping for too long, full C-West kit, Tein spring's, and KYB shocks. That's about it..but i'm looking for more performance and i was wondering if tunning would help me at this point. With the mods listed, would i gain good performance?
-Thanks for any advice
