I have since deleted almost everything from my engine that I can get away with. Fortunately, I never have to worry about low temperatures even in winter, so all of the cold start aids have been removed.
I have revised the factory diagram (copied from the back of the Owner's Manual) as I removed parts just so I could keep track of things for trouble-shooting.
Below is a copy of the standard system diagram and the diagram below that is where I am now. This is for a US 1986 930.
I have a B6 intercooler and small BOV which replaces the original large blow-off housing (19).
I don't have any problems with starting, idling or general running, although lifting off the gas a little at high boost brings on engine braking a bit abruptly sometimes, however I am getting used to it now and compensate with my right foot accordingly.
I hope this is of help.

1988 Carrera - 3.6 engine (with ITBs, COPs, MS3X) and a whole set of turbo body panels waiting in the attic.
Day job ...
