does your engine have an intake manifold banjo bolt & ALDA pressure line like the OM617? if so, that line be obstructed, starving the engine of fuel under boost.

a boost gauge may also be a cost-effective diagnostic before you swap the whole thing out. i just changed out the turbo on my car, but before doing so i got the gauge hooked up, found out where the pressure wasn't getting through, and found that my old turbo worked after all, except for its oil leak.
'77 240D, 504H, OM617.952, etc.
