Hi i know this has probably been covered before but couldnt find it, but i have an r33 S2 with 12psi, fmic, power-fc and dump pipe and cat-back, i was wondering how much power ppl reckon im going to have after my tune at boostworx?
i have previously with 7psi and just catback and fmic before my engine decided to start retarding due to a mechanic advanced my timing belt by like 3teeth on exhaust and 2 on intake luckily the cams were up when pistons were up and engine didnt demolish itself well anyway i was making 161rwkw so what do ppl reckon i will get now?
thanks
