Off the top of my head, too lean and your EGT's go up. And too rich, and your EGT's go up.
I don't recall what happened with my EGT when I played with timing.
Before my wideband, I tuned via EGT. As long as I hit 1500-1550 at WOT, I was happy. For each degree of timing I added in after hitting my ideal A/F via EGT tuning, I added a point of fuel to that RPM/Load range.
Granted this was for a turbo 4 cyl...
