So My 94 GT was loosing about 4PSI of boost. After researching more about the Forced Induction, I found that my Intake had two vaccum lines that ran to the PCV. When I pulled out the lines and shook the PCV it sounded fine. But when I blew through the PCV it would not hold any pressure. I'm putting the car back together this weekend and will follow-up on if this is the answer. Also after reading I have found that most Forced Induction people are taking their PCV to atmosphere with a Oil Air Seperator filter. So if anyone out there is running boost on their stock manifold they might want to check this out.
