Craig,

FWIW, Steve had two things to say when I asked about setting timing for my stock 930 track car (which, btw, has been running for who knows how long with the boost retard hose connected):

(1) Set timing at 10 deg 2 deg ATDC with the vacuum control connected.

(2) Factory spec is vacuum retard connected and if its run without it being functional, you WILL destroy P/C's.

At no time did he address max retard under boost.

That said, my local mechanic's opinion was to leave the boost hose disconnected and set the timing at 22 degrees ...
