That makes sense to me and what I have mostly thought. Retard with loss of vac.

Dose looking at how timing retards with Vacuum on the chart Roland posted effect what you are saying. It looks like it retards with increases in Vac, not advance. This makes sense for an SC but having a challenge with it for a turbo.

Still a mystery but my mind is open.
