They will start creeping up, but not until coolant temps exceed 230-235 degrees. I have seen mine start moving to the center, and then the fans kick in full blast and cool things down. This is only when towing really heavy louds in 90F+ weather.
I modify every other vehicle I own, and I have promised myself I will not mod the truck. It's really hard! It's like an alcoholic hanging out at a bar.

I went thru the same crap with fake Ford gauges on my 96 Mustang Cobra. I added gauges to my Cobra soon after I bought it.
I have the ScanGauge 2 in my truck (09 6.4L) now but would like to see oil temp. Anyone know how to get the SG2 to display oil temp?

I have the Dashdaq, with the spartan tunes, and let me tell you the dashdaq was definitely worth the investment. You can monitor every single parameter your heart desires, and you cannot monitor like 20 at one time! I feel much safer driving the truck with it. I know how to angle my plow to cool down the intake temperature, which in turn lowers all of my temps. Also its nice when I pull into the driveway, I can see how hot the EGT's still are and let that cool down which will in the long run save my turbos.

Thanks for the referral, Joel! 
I sent Mystic Cobra a detailed email about what I know of this. I'll be a bit more concise here.
As I understand it the scangauge is capable of displaying any value that's available through the OBD port. So theoretically it can display anything the DashDaq or Edge Insight can. The problem is that in order to get the manufacturer specific gauges you need the right commands...and most of them aren't easy to find!

The one you want to monitor is actually at the bottom right side of your image. It will be the hottest, as it is just outside the exhaust manifold (pre turbo, pre egr branch). The one at the top left is measuring the exhaust gasses post-cooler, to compare.

So I wonder how a scan guage would label it so you get the right one to monitor?

With a Livewire, I've noticed that the 3 in the exhaust (pre doc, post doc, post dpf) are all usually labeled in sequence; EGT1, EGT2, EGT3, making them easy to rule out. The sensor in the right exhaust manifold has been labeled (depending on firmware) PEGT, or EGRTA. Technically, it is an EGRT (exhaust gas recirculation temperature) "IN", and the one at the egr valve is "OUT". "IN" being the one you want, as it is the true EGT coming from the cylinder & manifold, passing through the turbo.
