Thanks for shedding light on this.

How does this MSD recognize boost?

According to the porsche manuals, my 88 is supposed to be set at 25-27 degrees at 4000rpm's (with advance and retard lines pulled off and plugged). After set and lines put back on, warm idle is at TDC.

With the MSD I can run several degrees ATDC?

I don't really understand "3 deg per psi, 20 deg max." Does this mean that... if at idle- TDC gives me 26 degrees at 4000rpm (lines off and plugged), that with MSD I can get an idle of 1- 3 degrees ATDC so that the MSD can retard 1-3 degrees on boost?

If so, is this safely curved for the span between idle and boost?

I know little about distributors and timing. Thanks for the education.
