    Boost issues

    Ive had my car running for a while now, and I havent been boosting it because I was trying to break it in. Now that that is done, I got on it today and got a whopping 3psi.
    The Granger has not been adjusted since it came off of my shadow running 14psi. The turbo is a new 46/68 T3/T4 with a big can wastegate. The preload is set properly to the pictures and instructions I was given by FWDP.
    Could my cam timing be the issue? the car runs to a T except for the boost issue..

    Could be a possible boost leak or your wastegate arm came off.

    do you get boost when you unplug the wg? Does it boost kind of slow? May want to pull the wheel off and make sure all the timing marks are lined up
