    boost?

    what is standard boost?
    my gsi is running 0.5/0.6bar well, holding it but does go upto 0.9ish when it starts boosting then dies down.

    im running both de-cats and full scorpion system, induction kit and fmic.

    It has a pretty new turbo also.

    is this normal or is there a boost leak?

    that is normal mate.

    a std mapped gsi will hit 0.8 bar over boost and hold 0.6 bar, works out at 12 psi over boost and holds 8-9psi
