What EGT's are u seeing?

Obviously for all you guys running an EGT gauge, post what temps you are seeing.

During regen at highway speeds I see 1200-1400* with or without my tralior. The funny thing is that it will never pass 1400* even if I try to push it while towing.

Normal highway speeds @ 70-80mph I see 650-1000* until regen kicks in.

A 0-60 mph run I will hit right around 1000*

650-1000? Seems to be a big difference. If you are just cruising flat what are you running?

Yes and No. Pulling a load the EGT's never really go over 1200* with out regeneration. I was driving through Tennessee messing around with a 08 V-10 Super duty up a hill through the moutains we were both pulling similar enclosed trailors, at that time the EGT's stopped out at 1200*. Although I've seen 1450-1500* towing up hill during a full regen.

So it all comes down to if the truck is regenerating.

Anyone using a Livewire to watch the EGT's? There are 3 sensors, (egt1, egt2, egt3). I only watch egt1 and see around 300C (572F) flat highway, no load, on 38's, stock gears. Are any of the onboard sensors good for watching or are they all for other computer related purposes (specifically located) and not the overall egt temps?

I think you temps are so low is because your egt sensors are back in the filter. Most guys want to know egts before they get to the turbo, what good is knowing the temp in the exhaust if you had already melted the turbo. My egt for my 6.0 was in the manifold.
