My early morning guess about the IP is wrong.

I've just checked in the W123 (turbo) FSM and chapter 07.1-001 shows that all of the OM617.950 ; .951 ; .952 have the same IP

PES 5 MW 55/320 RS 16 but with different governors depending on the year / non Californian / Californian

So the power increase can be attributed to the valve train as the bore / stroke / blah de blah is the same for all turbo OM617s
