Help, saab OG9-3 boost problem

Well I'm running a stage4 setup in my saab...downpipe/exhaust, intake td04 turbo, stage 4 software etc. I'm only getting 15 psi, this is down from an original 28 psi when it was hitting fuel cut.
I've tried 3 different ECU boxes, gutted the cat, swapped DI cassettes, swapped sparks, checked vacuum hoses, swapped BPC, manually inspected the turbo for damage and if it spins freely. Also checked the BPC and performed a smoke test with no leaks found. I know 15 psi sounds decent enough, but I was boosting up to 28 before. Anyone have any suggestions? It sounds VERY loud at WOT almost like a leaking sound.
