    Well, the whole thing is off. I realize my MAF is toast, but whats up with my boost? Maybe I'm reading it wrong, but 30psi? ko3 with a chip, 2nd gear.

    you have to subtract atmospheric pressure to get manifold pressure. you're about 16 psi

    Your MAF is toast for sure. I was getting readings of 130 and that was already on a verge.

    Get a reading of block 115 at idle since the atmos pressure will be different for everyone. Take that number and subtract it from your WOT readings.
