Installed EGT finally, quick question..
I did some searching before posting this. I mainly saw people post EGTs after they put a tuner on it. Was curious if anyone had some pre-turbo EGTs #s on a stock 6.0L.
I tried a few 0-75 mph runs with stock program, economy program, and performance program.
Stock program: 1100 degrees 25 psi
SCT Xcal:
Economy program: 1300 degrees 30 psi
Performance program: 1400 degrees 32 psi
I know I should probably get some aftermarket exhaust on it. Was just wondering if anyone elses got that hot on a stock program. 1100 just seemed a tad high when comparin to the tuned temps.
I love the look of the cobalt autometer egt

It improved power greatly. Ran a 16.5 stock in the 1/4, on performance tune it ran 14.22@94 with no other changes. Driving it around is so much nicer too, feels like a totally different truck. It did help out my mileage also. Went from 11 mpg around town to ~14-15 mpg around town. Unloaded highway went from 15 to 18 (got 20 on 1 trip on time). If I could keep my foot off the throttle it would probably be a lot more. Havn't tried the new max power tune yet, waiting for exhaust

Hmm, and both of y'all's EGTs are mounted pre-turbo?
edit:
I mounted mine almost exactly where this one is mounted on dieselmanor's install pictures. http://www.dieselmanor.com/diy/PSD3-gauge/image24.htm

Yes mine is mounted pre-turbo. Here is a link to a picture of mine from my gallery.

"The only time I have seen 1100 on my egt is when puling my trailer average right around 900 full throttle to about 75 at 28psi stock."
Me too with an all stock truck. Stock exhaust, no tuner.
Level road:
55mph - 4psi - 575 degrees pre-turbo
65mph - 6psi - 650 degrees pre-turbo
0-70mph foot to the floor going through the gears, empty truck - It'll hit
29psi - 1000 degrees pre-turbo.
Pulling a hill, towing my 6,000 lb camp trailer, @~3000 feet of elevation, 60mph (twisty road), although it would hold speed in fifth gear, EGT's were higher, (1200), than when dropping to fourth gear maintaining the same speed. ~18psi. I can see that I will want some exhaust modifications in the near future for those long Cascade and Rocky mountain passes later in the heat of summer. .
Sorry, I don't have my post-turbo gauge/probe hooked up yet.

Those EGT numbers match mine almost identically for my stock truck. Towing 8000 lbs up a good grade got me 1225 EGT. I put a 4" exhaust on to drop the EGT while towing, and got a reduction of 100-150. Last weekend towing trip the highest I ever saw was 1100, and I was pushing it on purpose. This is good. The bad is I lost 2-3 MPG unloaded with the exhaust change. Watch out, as larger exhaust seems to result in worse unloaded mileage. My towing mileage seemed to be uneffected however. I also didn't see any power improvement (or degradation), towing or unloaded.

Yes mine is pre turbo in the pipe between the turbo and manifold.

I pulled the manifold off to see that the thickness of the cast at the elbo wasn't what I expected. So, at the flat spot in the manifold between two cylinders I used the thicker area to drill and tap.
