Yes I have an EOT gauge. My deltas are about 8-10* apart at the most.
The coolant is around 185* most times.
After doing the pressure test, i am still just as unsure whats wrong with this truck.
If your deltas are good and your coolant pressure is that high with puking, it's head gaskets. I just went through the same thing, though pulling a grade with a load I could see up to 22 psi coolant pressure. It would essentially move with boost. I now see a max of 8 to 10 psi coolant pressure with no connection to boost. It just slowly rises with temp.
