on the 2.5 turbo, you cant bypass any of the emmissions stuff or it will
go in the limp mode and you will have no power. All the vacuum lines,
etc also have to be leak free or it will reduce power quite a bit.

Lots of possibilites:
Stuck waste gate, so the turbo isn't generating pressure sometimes
Leaking pressure line to ALDA and overpressure valve, or leaking
overpressure valve
Leaking transmission control amplifier so the boost signal doesn't get
to the ALDA
Dead turbo bearings. This can be
Lisa, unless you have a Mity vac, you might not be able to test them,
but I have found the vacuum transducers that control Alda etc. can
develop a hole and leak pressure, which can give mixed performance.
Excuse the question, but is there a clean pre and main fuel filter on there?
