Don't worry about the ideal gas law. This is a low tech very simple diesel engine. Stress DIESEL engine. There is no air/fuel ratio to worry about.
Your pyro pick-up is fine where it is. You need a relative temp so post turbo keep it below 1000 deg. Short spikes to 1100-1200 deg are acceptable but not for prolonged periods.
If you have a rotary pump (injector lines come off in a circle from the top of the pump) you have an Ambac Model 100 pump. You stated in an earlier post a diesel tech showed you the max fuel screw (if not, post it & I'll guide you) Turn this screw out 1/4 turn and road test. If you can't get your temp up under heavy load, turn it some more. If it comes up too quick, turn it back. Repeat until you are happy.
If you have an inline pump (injector lines come off in a straight line) you have a Bosch pump with RSV governor. If so, post this and I'll guide you through setting it up.

Good post, this is something I would have suggested, but I do not have that much knowlege of this engine.
I think you are all on the right track. I just want to put it another way. Since you have cooler incoming air temps and more room to play with on the EGTs you can starting adding more fuel. Since your turbo operates off the expansive gases, you should be able to raise your boost closer to the 15 you want by adding fuel. Also watch your tailpipe, if you are starting to get more black smoke I would stop there and try to find a way to get more airflow, but I doubt you will have a problem with that. Once you find your happy medium I think you will be quite happy with the power and still have a reliable engine.
