noise / whine / squeal on boost

I need help! I've searched the board up and down to no avail.
'99 9-3 base, T5, 165k
I'm getting a new loud "squeal" type noise as soon as I hit any boost, in any gear. There is no noise at idle or if I accelerate without hitting boost. I am not getting any smoke or performance issues, though I'm trying to baby it right now so I don't cause any damage.
What could it be? Failing turbo? Bearings? Vacuum leak? I've looked over the hoses and don't see any obvious leaks or connections that have come loose. Is there an easy way to test for leaks?
I have an MBC/+A installed which bypasses the BPC, so I don't believe that is the problem. Plus, that has been working great for years and this is a very new noise.
Any advice greatly appreciated. Thanks!
