    BPV and Boost issues

    Alot of people are having my problem it seems. I'm not achieving full boost. I only have an analog boost gauge, which I'm reaching about half way between .5 and 1. I checked a few of my couplings and havnt found any leaks. Could my BPV be bad? Any ideas?

    Also curious if anyone knows where our rev limiter kicks in. I've def more than redlined once or twice.

    its pretty consistent throughout gears. I only hit close to bar when I'm at WOT and higher RPMS. Still not reaching bar however. I had a friend ride along one night and commented that he thought he could hear a slight leak. Idk if hes full of it though.

    I thought it was just the turbo spooling to be honest.

    You and I have had this late night convo before about my boost leak. I checked my couplings. I just need to take my TMIC off and check my y-pipe sometime too to be sure.

    Idk. However it comes from the factory. I understand i should hit just under. But im hitting 2-3 notches shy of bar. Thats only about 11psi im estimating.
