I've heard and practice staying under 1350* most of the time. I don't like to see +1200* myself, but that's just me. Hitting 1400-1500* for a second or two shouldn't hurt anything as long as you don't make a habit out of it. Also incase you don't know, it's a good idea to let the EGTs drop to about 350* before shutting the engine down. It helps protect the turbo bearings from being damaged by the hot oil cooking off!

While cruising EGT's, with a properly sized turbo, should be in the 600° to 800° degree range.
Under normal load circumstances Gale Banks and most other diesel authorities, like Jay K.Miller, the turbo guru, consider 1250° to 1300° degrees F a safe turbine inlet temperature range.
If you see temperatures above 1300° you run probably out of air because of altitude or a compressor problem or your fuel system is simply overfueling.

Operating your engine consistently above normal accelerates wear. If you run above 1400° is just a matter of time when you have to pay the bill
