Just trying to think the last time I was "down the hill" (sea level). Can't remember! I can see some (not much) soot on the passenger side up pipe near the Y collector, so maybe this is a problem. I just ordered the boost tester from Dieselsite. Doesn't high EGT's go along with boost leaks? I towed 8K over the Sierras (thru Lassen Park, 89 degrees and 8000ft plus elevation) last September (boost pressure was the same then) and the truck did well, at no time did I get over 1200 EGT. I had the code erased today at a diesel shop, but it came back on the way home.
Until I get the boost tester, I think I have to check the MAP sensor somehow, or also look at the EBPV. Can an EBPV stick closed?
