Excellent photo Rugs.

Ok, time for me to stop screwing around, and install a boost gauge. Question about the pic above: I thought that you needed the boost sensor to pick up a positive manifold pressure reading from intake tubes between the intercooler and the intake manifold. How does a vacuum reading convert to a PSI reading. From the looks of that vacuum T, 15psi would blow those hoses right off the T.

Sorry for the noob question, but how exactly does this work?
