I'd start with your vacuum lines, blow-off valve and the BPC solenoid, and definitely look at the wastegate while you're there, maybe the nuts have moved. search this board for BPC testing advice and wastegate settings.
My leak ended up being in the dash's vacuum tubing(cracked hose to pressure gauge) but it could be a leak-through of a bad BPC which would dump all of your boost over base boost to the wastegate. BPC is easy to test. so is blow off valve.tracking a hole in a hose might be harder to pin down, but it's the cheapest to fix.
also,dont forget the little things. Like good gasoline. My aero runs like a dog turd on 87 octane,and like a champ on 93 since the ECU limits boost under lower octanes. Spark Plugs matter, and so does having them gapped right. Thought i rarely have sudden troubles from bad plugs, bad gas has had me looking for problems that aren't there.
best wishes and good luck.
