10:1 at WOT is not lean, that's rich, and will result in lower exhaust gas temps. This engine likes to run around 11.2:1 (or so) for maximum power and efficiency. You won't have to worry about high exhaust gas temps at that AFR.I leaned out my 1015% across-the-board and it screwed so crazy. Really want an egt. Worried I'm going to melt something. Knock -6 to -7 fuel 10:1 wot.
