Wondered the same some a couple of days ago, got answers, and of course, I found this thread AFTERWARDS:

If you dont have cat, I'd go for 12.5 - 13.0+. Brettus say that the gains from going leaner is second to none, and you'll have some overhead. If I remember correct, EricMeyer was under the impression that going leaner than 13.1 could shorten side seal life.

compared EGT to afr. keep egts under 1650 while leaning afr towards 13 from 12.
