i got bout 173rwkw with air filter, full exhaust, fmic, boost 12-15 psi and was running very rich from 11.0 to 10.5 at the top end and i wanna get my pfc tuned.how much power shold i expect after the tuning? has anyone had there pfc tuned on r33 gtst and did the turbo spool up quicker, better throttle respons ,more top end, better fuel consumption etc.
