Running hot at highway speed

Hey guys I have an 03 f250. I recently borrowed an edge insight from a buddy to check the condition of my oil cooler (witch is good) and noticed my truck runs hot. Pulling my 28 ft enclosed at 70-75 mph (in Ohio) I saw normal temps of222-232. It also runs 212-216 empty going down highway. The outside temps affect it slightly but nothing substantial. The truck is bone stock with now the addition of an edge attitude w juice. Since I have changed the fan clutch, thermostat, and water pump with all factory Ford parts and runs the exact same temps. The truck has 165,00 on it and I am the second owner and has been meticulously maintained. The coolant is very clean and it does not use a drop. I'm stumped on this one, and thoughts or ideas would be appricated. Thanks.

No I have never had it above level two ( tow tune). The teams are the same as they were with stock tune.

Well to be honest, I'm not sure what to tell you. Some will say you are running a little warm and some will say you are ok. I see temps like that here in CO and I haven't had any issues. I am running a tune though, which does make things a little warmer.

Couple more things for consideration:

Condenser, radiator, and CAC clean? Bugs love to get wedged into the cores and then dirt and road grime piles on. Hose it out really good, and from the fan side if possible (and yes it is a PITA with the shroud and stator in place).

EGR valve working properly? An EGR valve that is stuck partially open can increase operating temps.

Lastly, do you have (or know someone that has) one of those infrared temp guns? It can be very useful for diagnosing temp issues as you can run the truck and then take temp readings at various locations on the motor, hoses, and radiator to get a sense of where the problem may be.

As far as the condenser and radiator i cleaned those out when i had it all apart, but good call on the egr! I have not checked that and have noticed a little surge from time to time. I have not had one off one of these yet to look at it, do they still usually work well after cleaning or am i better off replacing it?

You can clean them, but be very carefuly not to get any cleaning liquid into the upper section where the electronics are. There are one to two small holes where liquid can get into the upper section if not careful. You will need new o-rings which are avalaible from Ford or International as an EGR valve service/gasket kit.
