Have tyrant tow tune and my egts seem to be pretty warm. Have the live wire with egt probe in the no limit block off plate. Anything I tow from 7k to 14k up hills in 5th gear speed limit of 60. I can get over 1200 degrees pretty fast and have a ton more pedal. I can barely hold 60 without seeing 1200. What do you guys see for egts. Thanks.

Towing 16k (same tune)uphill with cruise set at 65 in 5th I maybe see 1k, maybe check for boost leaks

Where are the common spots to look. Only pipes I have messed with are the intake which I put the s and b on and the cold side pipe that a switched out. What else could be causing higher egts? Thanks for the info.

I broke 1600* towing 8,000 up a slight hill the other day. It never downshifted from 6th gear. I’m pretty sure that is too hot. Tyrant tow tune in a 2015 dually.

What are you using to monitor egts. I talked with One Stop Truck Shop, which is where I got my tunes from. They said they usually don't have issues with high temps in the tow tune. I'm glad I did the deletes, but can't use anymore power while towing because my egts are getting to hot. Anyone ever monitored egts on a bone stalk truck. I'd be curious to see there temps.

I have a TCS Livewire with the probe in the EGR block off plate, if memory serves me.

That's what I have as well. I wonder if the probe and livewire software is not calibrated correctly. I don't want to tear into a bunch of stuff if it's just a bad sensor.

Did one stop truck shop happen to say what they considered high temperatures? I’ve heard that 1400 to 1450 is pretty common. With 6.7s

They said 1300 for short periods would be okay.

Damn!! Thats it!
