If memory serves me right, without pulling out the books to look at the timing curves (they differ with different years, BTW) I think at full boost it retards something like 8-10 degrees. Some of the better tuners on this forum can check me on that.
From the position of the adjusting nut on your distributor, it would appear you've got quite a bit of static advance dialed in....but then pictures can be misleading. I had to grind the slot on my dizzy so I could rotate it enough in order to get the advance I wanted, which was about 12* at idle if I recall (with both hoses connected).
Mark H. 1987 930, GP White, Wevo shifter, Borla exhaust, stock everything else. The result of a massive Pelicanite good will fire recovery effort. Truely an open book, ready for the slippery slopes to modification.
