Jerzey54, I specifically requested mine be installed pre-turbo. It's the heat coming into the turbo that does the damage so that's where I want to know the temperature. As MS said, there's a minute chance the probe could break off and take out the turbo. I've never heard of that happening so will take the risk. Post turbo isn't that bad a choice in my opinion but the temp swing won't be as rapid. My preference is pre turbo but that's just my preference.
As for cool down, if I pull into a parking space and the egt is below 500 I shut if off. If above 500 I let it run until it gets to 500. Only after a hard grade or long hot run do I have to let it cool down more than five or ten seconds. If in a rest area after a very long tough grade I may lock the doors and let it idle while we use the facilities. That's rare that we need to do that, though.
See another Montana or Mountaineer on the road? Flash lights twice, it might be one of us!
