Safe Exhaust Temp

Installed my Spartan and DPF delete pipe today, loaded the 275 and now I have a huge crew cab sports car.
I noticed on a 0-100 mph run that the exhaust temp reached 1600F.
What is a safe temp for this engine and how long can it hold it?

Set the warning for 1500f that way you got time to react to the warning. If you play a lot at the high temps you will cause problems, there's a reason ford defuels after 1100f in the stock tunes. Highest I could get on the 210 tune was 1350 and that took a long time to reach as thattune follows stock parameters in the computer. Have fun.

As long as you do not get it above 1600 degrees for very long, you will be fine.

Once you hit in that 1600-1700 range, it's time to start letting out of it. These trucks can handle pretty high EGT's in short bursts, but you never want to hold it for more than a few seconds. You have to start worrying about cracked valve seats at real high EGT's. Melting stuff would take a lot of holding 1600+ for a long period of time.
