I also note 1,8 bar boost... thats about 28psig!! I would've thought something would've failed or on its way to fail as the design boost is about 0,8 bar? 
  
Then you said its a regular OM617A, no changes other than the pump. So what pushed the boost so high? There must be some magic happening somewhere that I am not aware of. 
  
There is plenty about injection pumps I do not know, and I thirst for knowledge!

 I am going to speculate that more boost then needed to burn what Fuel the IP is injecting means more work for the Engine to compress higher density Air into the same space. 
 
I don't think that injures anything but I think it has adds a minsicule extra load on the Engine meaing a miniscule loss of performance.
 
The exception would be if you are at some high altitude.
