EGT is useful as a reference no matter what as far as I'm concerned. It'll help you figure out your combo, help with consistency and give you an idea to potential problems.

 A TQ wrench is useless if you don't stop turning when it clicks. Egt's are very useful when used properly/ Again location is very important. No magic number.  If your motor is fat at 1100 degrees its burning in the pipe.. I ran a top of the field TA/FC for few years using egt's to tune fuel system by. I could tell diver which bearings where beat out before he got pan off.  Also would tell guys which cylinder had good chance of bad leak test while they where pulling VC's.

 They work great for cylinder to cylinder tuning. Great to tell you if something plugged,pump going bad and general condition of system. ONCE  you know what numbers to look for and when. Just a tool and when used correctly very effective.

This is what I always went by back in the day:  https://www.ifamilysoftware.com/EGTreview.html

JEFF/21C:
It's a reference you establish a base line and change jets and nozzles to get all cylinders a close as possible  used both familysoftware and racepac on injected and blown motors with either you see changes where to richen or lean system it's just a tool like a scanner, pressure gauge or any other measuring device ! always check the plugs!
