EGTs high
 

I was pulling a small grade the other day, empty! My EGTs were at like 1150-1180. My truck has pulled that grade a million times empty and never got that high. Anybody know anything I should look into?

those arent anything to worry about. you can pull 1250* all day long and never hurt a thing. but i would look into a boost leak or change the air filter

How much boost where you running? You probably has a boost like the other guys suggested

or a slight exh leak in the up pipes
