Message	My MBC was originally set to 10psi and I wanted to set it to 15psi. I have tried to turned it both directions. If I turn it all the way (completely shut), my boost will go pass 18psi (up to whatever, which is normal). If I open it some (maybe 45 degrees), it will boost to 15psi and falls down to 12psi. Here is the tricky part: from there I can turn the knob either way a few degrees and it will still boost up to 15psi and quickly falls down to 12psi (desired boost stays unchanged). I am wondering if I have a boost leak or vacuum leak somewhere. Any thoughts?
