Question on max temps?

Hi guys/gals, I just want to be clear what my max temps are so I do not cause any damage to my 2002 F350 7.3L, 4R100 .

Before any one say, "Do a search" or "It on here a 100+ times" I did. Did I find any answers? Yes. Were they the same? No. Some would say one way then another. So if any of you know the correct or industry standard then please post.

To my understanding the max temps are:
-EGT: 1250 degrees, with the pyro in the driver side rear of the manifold. (where mine is). Someone said International says 1350 degrees is max but 1250 is very safe and can maintain that temp all day. True?
-Trans Temp: 225 degrees with then sensor in the test port. (where mine is)
-Boost: 30 PSI for stock turbo. (Mine is stock)

Thanks for all this great forum help!

Someone said International says 1350 degrees is max but 1250 is very safe and can maintain that temp all day. True? More or less true... Its about heat soak. You can go above 1250* for long periods of time, assuming you have not been near there for long periods of time.
-Trans Temp: 225 degrees with then sensor in the test port. (where mine is) More or less yes... If your seeing temps at or above 225 regularly, you need to add cooling capacity and or fix the issue.
-Boost: 30 PSI for stock turbo. (Mine is stock)25 is where your more or less pushing hot air...

Thanks for all this great forum help!
See above.

Thank you for the reply. So if I set my gages to alarm at these temps I should be safe or would you set them at a different range?
