Boost pressure C220 CDI

I can't find it anywhere, and it's really bothering me, so does anyone here know how much boost is the W203.206 pushing from it's 45mm turbo? She's a 2002 C220T CDI

Forget what VIN..? I knew/predicted/imagined it changes the boost depending on the load, but shouldn't there be like a, I dunno, average boost level? It just bothers and irritates me so bloody much that it can't be found anywhere... And I'll get her tuned after I've swapped in a 320 CDI turbo, which is 13 mm bigger than the stock one. Which, with my current level of bankrupcy, will be most likely in about 5 years :|
And I doubt the internals will pose any sort of threat since she's a diesel

Dunno how much different 4-cyl is from 5-cyl, but in 270CDI engine max. boost pressure is about 1,4bar. Full injection 75-75 mm^3 is given already just after 1 bar boost... air mass should be 1500 mg/stroke
