Simple question. How hot is too hot on a stock 6.0? I recently installed a tuner and can now see my actual oil and coolant temps. I run her on the stock tune and am seeing oil temps reaching 208 degrees F. Coolant temps are about 10 degrees less than that, all the time.
How hot can she get safely? Please and thanks.

 

PCM will start cutting the motor functions out around EOT 252* if I recall correctly.
