Yes, that has been my experience so far...(limited to only a few months of driving with a 
gauge) - highest EGTs of around 1500 (briefly) were easily achieved in a few seconds at 10-
12psi when fuelling was higher and timing less advanced. Now I can run at 15psi for long 
periods and EGT stays around 1200.
