My egts are higher when starting out in cold weather as well, till the drivetrain warms up. Then egt is lower after a few miles. The slower you go, the more miles it will take to build up drivetrain heat. Google "cummins secrets to better fuel economy" pdf. Numbers an charts an stuff. Apparently driving through denser colder air creates more aerodynamic drag as well. Makes sense, never thought about it till I read it though.
