Please help engine temperatures

It may not be an emergency but this is information I need to know before I go on a week long trip. I recently had a pyrometers installed, egr delete done, and have an h&s mini Installed. Now I was reading on another post that the pyrometers temperature should not be maintained at over 900 degree F for to long. My problem is that while pulling my 11,000 lbs 5th wheel trailer the pyrometers wants to stay at 950 and only drops below when decelerating or going downhill. Is this ok or do I have a problem. My other question is about engine over heating. My h&s tuner defuels my truck and takes any power setting back down to non. I have only ever used the mild setting ( I do have the head studs installed ). It does this at 220 degree F. I do not know the imperial system. Is 220 degree F actually close to over heating because my truck wants to run at around 225 to 230. So what would you say is the temperature in fehrenheit that would be considered running hot and then what temp is over heated.

Please any comments would be appreciated. I am new to diesels and don't want to be having troubles on this road trip coming up.

Is your EGT probe before or after your turbo?
If it's before, the general rule is 1200*F[649*C] sustained, short burst above that.
If it's after, take approximately 200*F[94*C] off the above.

220*F[105*C] shouldn't be close to overheating the engine. Do you know what your thermostat is?
