Sounds like Head Gaskets to me. Exhaust pressure building up in the coolant system.

No 7.3 in 04

Check ECT/EOT spread. No more than 15*

If you changed the EGR cooler you should have changed the oil cooler.

Tee in a gauge on the cooling system, make sure it's full of antifreeze and take it out and pound the hell out of it. See what the gauge goes to.

Does it overheat idling or just when you're beating on it.

Pull the shield off the top of the rad support between the rad support and the grille and wash all the dirt and **** out from between the radiator and AC condenser.
