It would be nice if there was some printed material to back that up. After all the Mercedes Service Manual has NA and Turboed Engines and as far as I know it lists the opening pressres as being different.
I believe that difference in opening pressures is also the same if you look and other makes like VW and Volvo diesels comparing the turboed to NA Engines.
