Your going to have to take off your intercooler and inspect the y pipe. http://www.wrxtra.com/Documentation/doc-1002.pdf <--This will show you how. Are your BPV bolt torqued right? Over torquing them can cause a crack in the intercooler which will cause a leak...

1-You need the car looked over by a dealer or a few buddies that know Subies.
2-Get a boostleak test done or do what Keith said and look under the TMIC for leaks.

Could this be another "missing pill" car?

gonna get it looked at by a subie guy today hopefully something gets figured out. i thought it might be the pill but i checked and it's still there unless it stopped function correctly all of a sudden.

Even if it was missing the pill it would at least run wastegate pressure...
