ECT/EOT temps - 8000lbs

Hi all, wanted to pass along my vitals from my first decent towing experience and get your opinions.

2006 F250, stock head bolts, egr & oil cooler stock.
80 degs F
8000 +/- 500 lbs with trailer and gear
34 foot travel trailer
decent up and down grades to pull with limited flat ground.
60-65 mph
A/C on, set at 70 deg
Using Matt's 8K tow tune

ECT - 202 to 214 degrees
EOT - 210 to 224 degrees

I averaged an 11-14 degree delta between ECT/EOT and only went over 15 for a few minutes and would come right back down and that only happened after a decent pull up a grade.

My reason for being concerned is I've installed an EDAS(Engine Damage Avoidance System) from POWERSTROKEHELP.COM - The Information Source for Ford Power Stroke Diesel Owners & Mechanics and Home of EDASŪ "Engine Damage Avoidance System" for Powerstroke Diesel Trucks and it went off when my EOT's hit 224 pulling up a grade. I immediately pulled over and let the truck idle and cool down for about 10 minutes. Do these temps look like I'm having issues? No puking and not low on coolant but worried that I'm towing less than 9000 lbs and want to avoid a complete motor failure if possible.

Thanks in advance.

I've hit 230F EOT and more while under heavy load with my 7.3 F250, such as climbing with a trailer. I don't think your readings are too high when towing a four-ton, high-profile load. Your water temperatures seem normal as well.

No, those temps do not point to any issues.

That system.....well...i will just keep most of my opinion to myself, other than to say that it would have been a whole lot cheaper to do a bit of research and buy a few gauges instead of some electronic idiot light.

Your thermostat does not even open fully until you hit 223°F or thereabout. The thermostat just begins to open at 190°F.
