[QUOTE="ZeroDCX, post: 14937398, member: 91953"] The MAF is not going to help with the boost loss. That's a mechanical issue. You need to figure out why it isn't compressing air as it was before. Are you sure you're not getting belt slip? Belt dust behind or around the pulley? The only reasons why it wouldn't compress air like it was before are due to boost leaks, belt slip, a bypass valve/bov failing or failing head unit. Another overlooked issue is, are you sure your boost gauge is functioning correctly? An issue that it could be is, depending in how the IAC hose is routed, the IAC could leak boost. But this is prevalent in non-intercooled systems where the IAC hose is routed back to the power pipe (before the compressor). It would leak boost, but could be remedied by a check valve in the IAC hose or by re-routing the IAC hose after the compressor, not before. Edit: A compression/leakdown test is also a good idea, too.
