Post STi next mod?
a friend of mine has an 05 STi, with txs turbo back exhaust, txs front mount, utec, txs recirc valve, injen intake, txs bc, and had it tuned they pulled 315 hp. he knows he needs to go bigger turbo but doesnt have the money at the moment. is there anything else that he can do for the time being?
