I have a 06 d12d 18 speed 4:30 gears.
I haul 140,000lbs and my pyro is usually at 600, on a hard pull I will see at most 650 and if coasting on flat road 500. can be 35 Celsius out pulling a hill at 1200 or 1800 rpm and not above 650.
if pulling hard and I go above 1850 rpm I will get a egr tempura ture value too high code which goes away when I drop the rpm again.
turbo boost is 35 to 38 lbs, no leaks in system. I pressure test each service. oil pressure steady at 60, coolant temp cycles normal.
just curious because I have read of guys hauling light loads with a d12 and way higher egts.
