Hmmm....she sounds to be in fine shape overall. Go for the boost leaks as described. All the plumbing to and from the turbo, as well as all hoses connected to the intercooler and manifold. Anyplace the boost could escape. It's gotta be there somewhere.

Don't overlook the WG. I do know that the valve stem and/or valve seats can wear over time and leak more than per design. In other words, some of that exhaust gas that's supposed to be turning the turbo can leak past the valve. It's' a pretty simple 10 minute chore to pull the WG and at least inspect it's components. Might see something obvious (like the valve not seating properly).

You'll find patient but thorough.
