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.

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.
I’m pretty sure these trucks can take much higher temps at short bursts not that I would ever push it that far on purpose but have seen posts on other forums of people hitting close to 2k in short bursts with no problems, back to the question at hand I would try looking for leaks with some soapy water around your clamps on the hot and cold side pipes and see if anything bubbles, also sometimes manually downshifting might be needed just because it’s maintaining speed fine if it’s getting to hot just drop it out of 6th and get that turbo spinning it will cool right down. as smart as these trucks are sometimes you can’t replace the human element in certain things the engine or trans has no idea of EGT’s so it will keep pushing until you drop a gear or let off or burn it up. But I wouldn’t be worried about 1,300-1,400 in a short burst personally.

Yes if you want to hot rod for a few seconds I'm sure that's okay. But I'm talking about towing long hills and passes for extended periods of time. I'm not sure I would like keeping it at 1200 when towing a pass for 45 minutes. As of now I wont be able to hold the speed limit of 70 with my egts. And that's only towing 7k.

Holding 1200° in these things is no problem I’m talking shorter bursts at 1500 and above these engines were designed to run much hotter than there previous versions which could take 1200° no problem I think your over thinking it a bit, on the flip side if your hitting 1200° pulling 7k and your not lugging the turbo then you might want to look at your tunes or check for a boost leak, the tiniest leak can cause high egts when towing

I’m sure the OP is wondering as well, any great ways to track down a boost leak??

I have yet to find any boost leaks. Done lots of searching the web and there are no good answers to high egt numbers tuned with tyrant and running the livewire sct egt probe. Lots do seem to have high numbers with this set up and no explanation as to why.

Stock 250 - monitoring with Edge CTS2. Towing 10K TT. Pulling long hills, I typically drop to 5th and run between 60 and 65. Usually keeps me under 1200. Any slight movement of the pedal will send it over 1300 and can bump off of 1400. Really have to be patient and light on the accelerator if I want to stay under 1200.

Now, when it regens.... on a hill, it's almost impossible to keep it under 1200. Fortunately, the regens are short lived when towing and they don't catch me on a steep grade all that often.

If that is what she runs for temps in stock form, it makes me think these engines were designed to handle 1400° without issue. I would guess that most folks out there towing are not monitoring their EGT’s and are breaking 1400 regularly as well. If 1400° was too hot I would think Ford would be having a lot of warranty work to do on melted pistons.
Thoughts anyone??

I've got a stock 2016 F-350. I hooked up a Banks iDash 'Super Guage' and it reads EGR's not EGT's. Not sure what the difference is. I'm used to EGT's on my 97 7.3 so this is somehow different.

Anyway, I tow a 9k trailer and going uphill here in NV I've seen over 1400°, but not always. Usually it's around 1300° or so. On the flats it sinks to 700° or so.

I've been Chatting on FB messenger with One Stop Truck Shop, the vendor I bought my tunes from. In addition to boost leaks, they had me check my coolant level in the secondary coolant system.
Below is what they said about temps.
"as far as temperature goes we normally recommend keeping it under 1350 degrees for extended periods of time if you did go higher than that a general rule of thumb is the higher you go the shorty want to hold it there. On other vehicles with a hotter tune we have pushed in well above 1600 for brief spurts. Situation is like hammering down and getting onto the freeway or getting up to speed or drag racing stuff like that. I personally have gotten up to 1800 degrees during a 30 second or so race with no issues caused from it."

He also said "we can always get a revision for you and try to turn the fuel down a little bit on the top end to see if it helps"
