So, could "timing being retarded/firing too late" cause "higher than normal EGT"?  Anyone else think there might be a timing problem if someone reports "higher than other folks' EGT"?  Not making a "dogmatic statement" this time, just asking for a sanity check or other operational anecdotes.
 
 
Hi David,
 
Timing can certainly cause high EGT's, but I did the usual test with mine on the ground, and thought it was the same as before.  Basically, I ran WOT, adjusted the timing via mode # (I can't remember).  I found the highest rpm to be a couple clicks above where I was already set, so I left it there.  I might consider advancing it some, but it's easy to tone down the temps with the mixture.  
 
I believe the temp "limit" for 321 stainless is 1800, so I'll try to stay under that... unless I need some impressive number to beat Ed with :-)
