If you are confident that your air is all tip-top, then we need fueling numbers. You won't get that without a bunch of expensive gauges and a lot of work - or you can get them in an instant with an OBDII interface and software/app.
The HPOP is not the common failure point. Air in fuel, bad ICP sensor, bad IPR, leaky injector O-rings, bad injector internals, and hot tunes are far more common. Of course, you'll have no way to know this with the lonely EGT gauge and boost gauges.
Yah I certainly wasn't trying to imply that the hpop was a common failure point but for me it did immediately drop my egts. Before the hpop 'popped' I had been all through my truck and had hunted and hunted and found nothing, not being able to 'scan' it with proper software. Point being you're 100% correct in you need the basic software to get the readings/numbers otherwise you're really wasting a lot of time and potentially money 'guessing'.
Have you checked your turbine exhaust wheel, im working on one at work the thing looks fine at first glance but in a closser inspection the blades are melted all the way ill take some pic's tomorrow that was the root cause of high egts on this truck
no I have not looked at my turbine exhaust wheel. I have only looked at the intake side. Would that affect boost? I guess I will look at that when I drop my down pipe.

This particular truck was boosting low im going to say 5 lbs less than stock but took forever to do so, at (3200 rpm) and egts skyrocketed. no boost leaks, no exhaust leak, everything checked out till i removed the down pipe and found what you see from my previous reply
Not that many may be interested, but I went through quite a few courses of Thermo back in the day... this is a great elementry link explaining Qin within the diesel cycle...
Someone mentioned EGTs and density of air.. This explains it perfectly... For real world experience, go pull a steep long grade at sea level, 5000ft of elevation, and then pull the Eisenhower tunnel with 20k lbs behind you.... Your EGTs will jump 2-300 degrees from sea level to the top of the tunnel at comparative speeds, weight, and gear/rpm. Denser air makes a big difference on EGTs!
I have officially seen 3 burnt up exhaust wheels on stock programmed and injected 7.3s in my life, and that one is the worst by far!
