P.S.I.cho

My 03 cobra with a kb 2.2 seems to have a large boost leak. I've used a vacuum pump to test the bypass valve it moves freely and holds vacuum. If you stick your head under the hood and snap the throttle you can hear large amounts of air (similar to a shop blow gun) but I can't seem to feel any with my hands. The car makes 0 boost right now. Any thoughts?
