Update: i need some advice and i havnt really had a good chat with sean at ASG, im not planning to upgrade the vf34 anytime soon and im starting to hate the lag the front mount is leaving me with so i had my mind set on a process west TMIC, gavins Spec C TMIC popped up so i grabbed that of him, but now i need some advice on what to do regarding the p20 on the vf34, im going for bigger injectors and putting the headers on aswell is it worth putting the p20 on?? and how much of a difference will the Spec C TMIC make??
