Thermostat maybe??
I have a 04 350 with a 6.0 165k on it and I've used the blue driver 100$ USB plug in to "read" some of the trucks issues and or use while driving and the coolant temp never gets above 169 no matter the weather outside. I was wondering if anybody has ever used this and if it's accurate at all. The truck runs fine have no issues but still worried about it.

Another option to verify data, would be to post up your general location to see if anyone is close enough to bring their scanning tool over and/or check in the Chapters section for the one you are in/near and ask there...
On your device, what does Oil Temp read?

FIRST: Check engine coolant temperature and oil temperature AFTER about a 12hr. or longer cold soak to see if they read the same. They should be very very close. If not then record the temps and swap the sensors (they are identical) to see if you can repeat the results. If the temps move with the sensors then one or both are bad and a heat gun or instant read thermometer can help tell which is off.
As 69CJ says, it wouldn't hurt to change the thermostat. IMHO they aren't very long lived and frequently go bad. Regardless, you should be running at least 190*.

Thanks y'all for the input. amdriven2liv I'll do that thank you. About how long does a T stat take it doesn't look to hard. Yes I have some experience as a diesel mechanic. Not the greatest by any means but I've got some skills. I'm located in Oregon so 3/4 of the year it's cold and rainy. Npccpartsman what is a cold soak? Are you talking about letting it sit for 12 hours without running?

If you can wait even longer, do so, or if it is pretty cold where you are, 12 hours might do it. Check those temps when you turn the key on with engine off.
I'm not a diesel mechanic, tho I have turned some wrenches prior to my body going south on me, and even I would do my own thermostat -- the other guys here will get that, it isn't anything towards you... If those temps look close get your shirt sleeves rolled up!

Edit: your looking for a bad temp sensor 1st....
