Why in the world did you post in an old thread in the 7.3L PSD forum? 
I cut your post from that old thread here, but I had no idea I should have also moved the subsequent new thread over to the 6.4L forum.
I'll fix it now by moving this to the proper forum for you.

Like all forums, FTE is broken down into categories to organize the information presented for the user.
When you scroll through the forums page, look for the diesel category, then look for the forum that covers your engine. In this case, you would look for the "6.4L Power Stroke Diesel" forum. That's where this thread is located.

Your EOT should only be about 4-6 degrees hotter than your ECT. My ECT is normally 199F and EOT 204F under load. My EOT ran up to 230F + and my truck went into limp mode. Ended up being my oil cooler. It got clogged with universal green antifreeze being mixed with Ford Gold Coolant, causing gelling. It's a cab-off job so it can be quite expensive to replace.
