Procharger Diaphram Hi!
My car worked fine until this drive through lady at Taco Hell had me shut off my car cuz she wouldn't hear me. When I turned it back on, the vacuum gauge was reading only about 5. Normal vacuum for idle is about 20. Then it only goes 1-3 PSI into boost. I called ATI to order some parts, and asked him about it. He said I probably blew a diaphram in X, or a vacuum line. I forgot what part he said, but I think it was between the intercoolers and supercharger.
Is he talking about the bypass valve? The action on the valve seems to be fine.
I have a P-1SC set up on a 99 Firehawk.
What steps would I take to figure out where the problem is?

Where is your vacuum/boost reference source tied in for your boost gauge and bypass valve? Sound like the leak is before these two components. I would check whatever hose they are tied into first.
