    boost??

    owner of an astra sri turbo mk4, running just over 270bhp, it boost at 22psi then drops down to roughly 19-20psi after a few seconds, is this too high?, dont wanna be payin for a tone of things if its running to high boost, i can see on the boost gauge were it tops out at.

    my mate owns a mk5 turbo astra running just shy of 300bhp, his only boost's at about 19-20psi, then drops to 17-18psi??

    if anyone else boost so high ar has anything i should no, it would be much appreciated!

    That sounds bang on for Phase 3.5.
    Some run a bit lower, some a bit higher.
