Have you had the truck long? Is this the first summer or first time measuring temps via OBD? What’s the status of the cooling system?
I just got the BlueDriver because I had the EGR ERROR code.

I kept the EGR delete kit and ordered a new clutch fan from Wits End and installed the auxiliary fan. I also ordered a new radiator and hoses but haven’t had time to install them.
The new blue clutch fan and auxiliary fan makes a difference but it still does go above 200.
I believe...(could have this wrong?) that the EGR modulator function is - that it enables EGR only when there is moderate exhaust gas pressure, i.e. at mid throttle and mid RPM, which is when fuel mixture is under closed loop control, and things can be optimized for emissions, etc. BUT-when you are climbing or accelerating - exhaust gas flow and pressure increases above the modulator threshold, and it shuts off the exhaust re-circulation path, so that system doesn't have to cope with extreme heat loads.
So-if you have deleted/disabled EGR-it's always just in the "normal" non-recirculating condition, and so - that cannot be the cause of your overheating?
