    Hi fellas
    I need to know if I need a de compression plate or not on my compound turbo build?
    its going to have the potential of running high boost which I know ant good!
    turbo I have is a garrett gt2554r and still to get a gt3071r or hopefully a gtx3071r
    at the mo it has all forged je pistons cr: 8:75:1
    ADR Large port head and full supertech valve train std cams and lifters.
    large inlet manifold full 3" threw exhaust.
