Engine Coolant/Oil Temperature High?

Hey fellas, looking for some feedback on something I noticed just the other night.

Truck is a 2010 6.4 w/ 21,xxx miles tuned with Spartan 250 LL tune since 8,xxx miles. S&B Intake, 4" Diamond Eye DP back exhaust, no muffler.

I was driving the truck just last night when I got an alarm on my DashDAQ telling me my engine oil temperature was too high. Naturally I freak out, pull over and shut her down. It was about 75* out, and I was driving approx. 40-50 mph through some rolling hills, nothing steep or crazy, only 1/4 throttle or so. Coolant Temperature was 194*, Oil Temp was 200*, Transmission was 171*, and Intake Air Temperature was 81*. Now it's been a good while since I've driven the truck daily, and up until this point it hasn't alerted me before. However, just a month ago or so I did lift it 2.5", put on 36's, and add a dieselsite coolant filter.

What do you guys think of those temperatures? Am I just paranoid because I don't remember what the truck used to run at before the mods? When I flashed the 250LL tune I did get in there and mess with the alarms and may have just set the Oil Temp Alarm lower than I used to have it, thus causing this worry-fest.

Go give your inner powerstroke child a hug and whisper in his ear that everything is just fine and stop being so paranoid. That alarm is set wayyyyyyyy too low.

Haha just the answer I was hoping for! It's tough not to step into a world of paranoia when you lurk the "6.4 Problems" forum, but I just wanted to get a second opinion!

Mine typically runs 196/196 with slight variations. In the heat of the summer and extended highway drives, my oil will usually run 199-201.

I ran those exact temps today with about 60*f outside. I also sort of think these numbers are high but not sure. Just this past weekend I put in the Mishimoto radiator and wasn't sure if my numbers would drop. They didn't. Maybe I'm just paranoid too.

Mines actually getting betteter the more I drive it, almost like it was working some air out of the system. Try opening your degas bottle cap just enough to let it breathe and go for an easy drive to keep coolant from sloshing out an d see if that helps!

I'm with NYC on this. Those temps sound fine. I wouldn't want to see any of them much higher though.
