This is a good question you pose, CLAYTON. I'm often changing the display around on my attitude (almost daily), looking for the most useful data. Interesting that, based on the responses, choices seem quite variable.
Looks like EGT is a given, but the rest ?.
I tend to display boost pressure, throttle %, and intake temp (in addition to the Pre-turbo EGT) most often. My Autometer's are showing: Post-turbo EGT, Trans temp, Rear Diff temp, and Fuel pressure.
I'm curious, as you are, to see what others are doing.
