A friend of mine has recently fitted an uprated fuel pressure regulator to his 2.0L 16v Golf which increases the fuel pressure to the injectors, he claims there is a noticeable

difference in performance. If I fit a similar device to my vRS will it cause any problems, as my car has been remapped with 230bhp? I have recently fitted a cold air induction kit and I'm thinking, More air, so More fuel wouldn't hurt. Any one got any thoughts?

Is that what's commonly termed the 3 bar FPR?
