Greg, at WOT my engine's sweet spot is 32* and I currently have my distributor locked out at 32*. I can however retard the timing either by set RPM or vacuum with my ignition box. I currently have it retarding the timing at high load, low RPM instances with the MAP sensor and boost retard function to prevent pinging when driving on the street.

These engines will idle cleaner and cooler with 37-40* of timing and cruise timing (just off idle with a light load) also likes some extra timing. The way to accomplish that with my setup is to lock the distributor in well advanced (like 45*) and retard the timing via either RPM Run retard or Boost retard with vacuum signals. Doing this will help (a bit) at idle and heavy load, no vacuum, low RPM instances...but do nothing for WOT high RPM runs.

This is one of those street car vs race car battles that I constantly find myself in. Race car won this round, even though it still drives pretty dang good on the street too.
