Other suggestions? - full standalone engine management with knock sensors. 
Is anyone else with your engine in the same climate having the same problem? When you say lean to rich running conditions, where is it lean, where is it rich?

Hmmm...maybe I will retard it.
Full standalone...at $5K?
It actually doesn't run lean at all. It ran fairly rich during a dyno run, then we enrichened the mixture even more as it got hot out here...
