Running a little hot? Not oil temp

[Kevin7898]

2005 isx, egr position sensor has malfunctioned leaving the egr closed. But egt seems a little high. I might have 6k lbs on the deck. This a normal temp for a non egr engine? I've never driven one without it and never saw over 600 on a hard pull up a mountain. Just wondering if there is something else the boss and i should be checking. Finally broke 6mpg last week grossing 90k lbs which is nice. Just over 7 with this load. Ignore the restriction guage. It's broken. Just put in new filters 2000km ago when we did an oil change and full filter change. Oil was a dark brown but not black
