I expect to be questioned about it but since I don't have and never have had a chip or programmer on it I'm not concerned.

 

if you hit 1500 degrees then you just more than likely cracked your DPF. If you start seeing 1300 degrees, even during regen, then you might be seeing an engine problem. Maybe an injector leaking or something like that. You will usually see temps of about 1000 to 1100 degrees. Like I said, 1500 degrees is WAY too high.

 

Incorrect. There have been guys that have hit 1800 degrees racing these new 6.7s. Lots of testimonials of 1600-1700 degrees when pulling heavy. I won't worry about EGT's unless I see upwards of 1600 when in regen.
