Turbo Trouble (MOAR BOOST but not on purpose) 700

Update:
Checked out the turbo to wastegate actuator hose and found it was semi-plugged with what looks like coked oil. Also looked like the same thing was in the diaphragm nipple.
I cleaned it out and replaced the hose (the turbo side was brittle and heat-bonded to the nipple) with some fuel/emissions hoses. I'll have to get a legit volvo hose, but it should work for now. The ID is the same, and it's reinforced, but the OD is huge and I can't fit the clamps on it.
The hose didn't seem to be leaking.
It looks like the TD04 is easy to disassemble (one clamp and splined for alignment), so maybe I will pull it apart and see if the wastegate is all gummed up.
If so, easy fix, if not.... I think the diaphragm must have a hole in it.

Thanks guys,
Will

PS I think the fuel pump cutoff switch is missing (or moved) because the engine was swapped out at some point... yaaaay frankencar :|
Happy holidays :D new brake pads tonight.
