(Incidentally, he said that the best thing that EVER happened to
their business was everyone running "lean of peak" and driving their EGTs up
above 1500 degrees. As temperatures approach 1600 degrees, the metal simply
starts to fail, and you end up saving pennies on gas, and blowing dollars on
exhaust systems.)

1600º is LOR (Lean of Rich) not LOP. 1600º is right at peak, as has been
stated. My engine typically peaks at 1590º. With the BMP (Big Mixture
Pull), I go from ROP through Peak to well LOP in about one second.
Yesterday on my flight I was running at 1490º, or 100º LOP. Now, if I
run it 100º ROP, what will my EGT read ?

BTW - my CHTs were 320º.
