Just wanted to give an update, swapped out both sensors and did the same run, one at 65MPH cruise, and one at 90mph beating it down.
At 90mph the oil temp never went past 205* and the coolant want around 190/191 so 15* delta there.
At 65MPH I saw about a 13* difference coolant was still 190/191* and oil
Temp was right around 203* dropped to 202 once or twice. So I would say the sensor were PART of the issue but then new egr cooler is probably partially clogged already.
Again, this was not on flat ground but very hilly highway, but I wanted to have the same scenario as when I saw the 20* delta.
In the time it took me to write this with the truck idling the the coolant temp is 188* and the EOT is 191

That was before the Mishimoto 202 thermostat. Deltas are now around 6 degrees, but then again outside temps have dropped and I'm not running a/c anymore either, if that makes a difference.
