My D350 crewcab, with 89 motor is all stock....164K miles. Cruising at 65mph I see about 2-5lbs boost, and my post turbo EGT is around 450-475 degrees. This is with my NV4500 in 5th, and 3.54 rear,

Different conditions.
I put my winter front on last weekend cause my thermostat wouldn't stabilize.
Cruising across the hay flats at 55, -4°, stiff head wind.
Boost came up to 12psi and egt to 800° in 5th.
Thought my engine was trying to quit until I looked at the boost.
