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

Out Of Control!!
Forget the VIN there is no specific reference to design boost bar in documents and that makes sense because the CDI control module is mapped to read the input signals from the boost transducer and allow or vent the bar generated for design performance
However call any tunner because they must know the boost map, which they will modify to supposdly get extra performance.
That is dangerous without knowing whether the stock pistons\rings will take the added pressure, but the tunners could GAS about that. All they want is your credit card number.

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
