The banks power pack comes with a EGT guage. That EGT guage is installed in the first bend in the down pipe.
In the manual they state that the EGT guage should never get over 1100 degrees. They do not mention the amount of temp drop from the manifod to the down pipe.
Say whatever you want about Banks, but I tend to trust their research.

I think banks simply installs it in the downpipe for ease of installation.
(click here) that is what you should follow post turbo.
(click here) this is what you should follow pre turbo.
I dont trust banks research with the use of the stock air box

Well that might settle it because the Isspro three gauge kit I have comes with the R658 thermo. Recommended for post turbo.
Don't recall seeing any specs like that when I ordered the kit.
What I might do is put it in the pipe first. Record my temps under different conditions and then put it in the manifold and compare.

That would be a great comparison. Not that the gauges don't mean anything, but if you could do both locations on the same truck, same mods, etc., there really couldn't be any arguing that. Unless you would lie to us for some reason.

Here is the excpert from the Banks manual regarding EGT temps when the pyrometer is installed post turbo as it is in their kit
Use your pyrometer gauge to monitor exhaust gas
temperature (EGT) in the engine. At idle, EGT will be very
low, perhaps only 300°F. As the engine accelerates and is
under load, the EGT rises. The safe maximum for the EGT
is 1050°F. The highest EGT occurs under maximum load at
full throttle, such as climbing a steep grade with a heavily
laden vehicle. If the vehicle reaches maximum EGT during
these conditions, downshift to reduce the load, or back off
the throttle. CAUTION: Exceeding 1100°F can cause
engine damage.
My truck was run with the stock airbox for 100,000 miles with no ill effects. The turbo compressor wheel looks like new.

<a href="https://www.ford-trucks.com/forums/493621-egt-findings-pre-vs-post-turbo.html#post3684558">Click here</a> to see what someone else found by installing both pre and post sensors. Would there be any temp differences between a 99+ and our 7.3's?

I have a Banks kit w/ the EGT probe in the dp at the bend out of the turbo. My Banks manual concurs w/ WR's info. I've hit 1050 hauling several times and 1100 once unintentionally, with no problems. But I back off when it gets that hot and try not to push it. Level cruising at 75/80 hauling 7-8Klb usually stays around 600-700 post turbo. One of these days I'd like to install an EGT pre turbo, but to be safe you need to remove the exhaust manifold. Don't want to get any drill/tap shavings in the turbo.
