What mod's newage sti
 

Hi i've had my sti widetrack for a year and engine wise its completly standard, it hasnt got the ppp fitted, all i have is an afterburner back box.
What should i be looking at to get 330bhp ish? The stuff im thinking is de cat down pipe, fuel pump, and a re-map.
If i take my car to fb tuning can they re-map my standard ecu or do you have to have ecutek or similar?

any thing else i should be considering?

thanks
