While discussing pro's and con's of mods with a friend the subject of EGT's came up. When towing, I am sure that you can exceed your threshold of EGT's easily with a stock set up. Buddy wasn't so sure, stating why don't diesels come stock with a pyro then? Does the truck recognize temps and adjust? Suppose you wouldn't know until it was too late.
I think that within a few years one of the big three will come out with a pyrometer gauge. What do you guys think?

I would think that if you had a clogged air filter, you could get it too hot.

The stock programming is pretty conservative. In stock form, my truck wouldnt exceed 1100 degrees. 1250 is the safe limit, so I had a lot of room to spare. Even with my 10k mod, an open filter and gutted muffler, I was still under 1250.

In bone stock form, you should be able to tow at the max GVW and not worry about high EGTs.

I do know there are a couple of factory ford computer codes that are known to run a little hot, but I think Ford catches them on service calls and reprograms them without telling you.

I am stock except for a turbo back exhaust and I have pulled a 4000 lb trailer up some passes in the mountains (and not the real big mountains) and got over 1250 and have seen almost 1300. I let off and or let it down shift and slow down some and proceded on. I wouldn't have thought it and was glad I had a pyro to see it. With the exhaust, I would have thought I wouldn't have come close to the temps I have stock but did. Go figure....

Im assuming this is on your 6.0 truck. Are you up to date on all your computer flashes?

Also, Im not 100% sure what the "safe" numbers are for the 6.0s. The 7.3's with the garrett turbo are good to 1250, even a little higher if you factor in the time it takes to fully heat soak the parts to actually get them to melt.

6.0s are a different beast. What with that variable vane turbo and all. A 4000lb load shouldnt even make these trucks breathe hard, let alone overtemp the turbo!

On my early 99, when I still had the XLE8 pcm, stock 'cept for at the time a Amsoil filter and gutted cat and Walker BTM...towing our 27' TT which was roughly 7k...I hit 1200-1250 numerous times and had to back out of it.

Well, not "easily", but some stock PCM codes will get over 1,250º under extreme conditions of towing a heavy trailer up a steep mountain pass at wide open go pedal. So if you don't have a pre-turbo pyrometer, then limit speed when towing up a mountain to about 55 MPH, or about eight-tenths of wide open.

With my excellent intake and exhaust, and the Edge Evo programmer set on "Tow", I can maintain about 60 MPH up the hill when grossing 17,500 pounds without too-high EGT. When grossing 16,000 pounds, I leave the cruise control on 62 and hang on while my BTS tranny downshifts and my hot-rod towing machine takes the hill. /ubbthreads/images/graemlins/warmsmile.gif

Like they all say all trucks are different. My X would go over 1250* stock pulling a 5.4k TT up Vail Pass. Had to watch the pyro.

Just my situation, so yes stock oem can go over.
