In "Porsche 911 Story", Frere stated that the 930 was .8 bar and the 965 was .7 (the digital boost gauge in the 965 only reads to .7 bar). I'm not sure that is completely factual but I haven't seen many errors in that book. For some reason the factory upped the boost of the 3.6 engine and added hotter cams, as you have stated.
