So freeway speeds around 75 mph I read between 700-800 so if I add 100 to that because of my location I'm running800-900

700 sounds about right.

I know it's a Duramax... But Im seeing 500-700 daily driving. And 1200 Max at WOT. The WOT numbers are very low for a truck like mine but Ive spent alot of money getting parts that help EGT's for towing. Average for a Duramax at WOT with mods for racing is 1500 degrees in the 1/4. My probe is drilled and tapped in th BD drivers exhaust manifold.

Good to see the Ford's aren't much different... But 200 degrees seems really low. That's what I am at idle.

Ya I got it figured out works a lot better now

I haven't broken 1000 degrees yet, according to my black maxx, but the only thing I've hauled is my 1200lb ATV.

I'm usually around 700 @ 75 MPH... Using the factory pyro right now, so wherever that's located...

Lol I have hit 1650 on the 1/4 in Vegas. Cruising it's 8-900. But I am at 7400 feet and I find my toe tunes runs a lot cooler. Doing the summit (5% upgrade and a 1300 foot elevation climb in a few miles) and I hit 1100 tops at 80 mph.
