Watch air fuel would be a better way to make it safe.
Egt can be hi just from too much fuel or low timing.

What would too much fuel be considered when lugging up a hill in boost in OD?

I agree with the above. EGT is very misleading.

I would never go above 1400 degrees pre-turbo. drop at least 200 degrees post turbo.

The reason its misleading is that you'll be sitting at 1400 just tooling down the road at low throttle (14.7 AFR) and you can sit at 1400 degrees under full throttle (11.0 AFR) depending on timing. intake and cams can also drastically change this. I dropped 200 degrees on a 4 cylinder back in the day to a total egt of 1200 but still toasted the engine due to too much timing.

Most hurt there engines right before or at peak torque, which your EGT will be too slow to catch.
