Do you have any idea what your EGT's are? How hot is HOT . . ?
I would caution you about using another or previous engine as a true benchmark. If this engine is running "Better" than a previous one, it could be that the previous one wasn't tuned as precisely as the current one and your EGTs are OK for the tune you have on that engine. That's assuming all your other markers were correct.
You possibly were on the rich side previously, dunno . . .
