You should seriously stop driving the truck. Normal Ect is 190°. The oil temp should not exceed 15° greater spread, that would be your delta reading. Check both of yout temp sensors after it has cooled overnight. They should read close to each other within a degree or so. At the temps you posted, your truck should be defueling. If I was you, I would flush the cooling system, replace the thermostat and the water pump, then recheck deltas at op temp on flat ground at 65mph. How are you reading pid's?
