1) "Before the pitch change EGT would hit 1328 (720c) on cruise."
2) ". . . removed all but 1/2 degree that I added."
3) "Now temps at cruise run about 1292 (700c)"
4) "a small increase in climb will bring them down to 1256 (680c) or
even a little less"
You've shown a 36F/20C reduction from a 1/2 degree change in pitch.
I'm assuming you are still running the same 1/2 degree addition to the
prop pitch since it gives some margin on EGT. What is also important
is you've given some quantitative numbers of the drop:
1328F/720C - original
1292F/700C - new cruise with +1/2 degree
1256F/680C - slight climb with +1/2 degree
