@ JR, have you ever thought that maybe your EGT's climb really fast when "hammering" on the highway because the pump is turned up too much on your N/A truck? The guys on oilburners.com suggest turning up the pump in 1/2 flat increments on N/A IDI's.

I know a pyrometer and an EGT gauge are the same thing, I just threw that comment in there because the OP wanted to turn his pump up without one.

My buddy had his 6.9 with a 7.3idi pumped maxed out. Ran her for over a year till he sold it like that.. didn't burn anymore oil than before. Beat the living hell out of the thing too. No pyro. Ran that sucker up a mountain pass with a boat in tow flat footed the entire way up the hill at 35mph. Don't know how hot it got but ran perfectly fine. I dont really see how you could melt one of these engines.

A stock N/A IDI can hit 1200* on the pyro fairly easily. Thats why turning it up some makes things scary. Can it survive? Sure, look at the poster above ^^^ but I would chance it. I want to kick the engineers of the big three in the nuts everytime they come out with a new truck, and they dont have a pyro. Its important to have, and gives you good baselines to base things.
