Thanks for all your help. This is really interesting.

Sorry, not on a dyno, simply seat of pants.
Stock 3.3 liter 930 with SC cams, no intercooler:
0.8 bar boost, no vac advance, 28 deg at idle, 46 deg at 4000 rpm, 38 deg at full boost. (With vac advance, timing as adjusted would be 8 deg advance.)
1 bar boost with vac advance, 2 deg advance, 40 deg at 4000 rpm, 29 deg under full boost. Don't know if this timing is optimal but not willing to pull the pin on the grenade in the back seat to find out.
With a handle on AFR, one needs a dyno to establish optimum advance/retard equation. Having ability to monitor knock (detonation) would help minimize dyno time and resultant engine wear and tear too.
