I think full boost enrichment usually comes in at 6psi. (not sure). If so, should the MSD be set to begin retard at 6 psi and continue at either 1, 2, or 3 degrees per pound till 14.5 (1 bar)?

As you had mentioned, there is already a boost retard on the stock system, so, once we figure out how much, is it then just a simple equation or is the combo of the stock retard and the MSD retard a recipe for disaster?

Instead of idle at TDC as it is currently, if I set the idle timing to 3-5* ATDC, how will this affect non boost cruise at 3000 or 4000 rpm's? More power or might it miss?

When boost pressure kicks in, I've already got the stock retard. Is the only advantage to this system that at low rpm's timing can come in sooner, or does this system allow quicker timing on boost too? (I don't know if this question makes sense, but I tried.)

Thanks for your detailed answers.
