Hotter Turbo

What are the highest SAFE EGT's on my turbo should be run at?
I have a 2000 ford f350 and I was wondering how hot my EGT's can get before I should worry/back off th throttle at. I would like to know what EGT's should be at for short bursts of speed/hard acceleration & steady hauling over a long period of time
On the dynamometer we back off at approx. 1700 degrees F
