Ive read of the diablo making the EGTs too high..Even when towing 19K, i have yet to see my egts get +1300. I have the pyro reading the 1-3 cylinders, which dieselmanor says it will read significantly higher? Am i lucky, or is it a false reading?

 

Sure, it will make your EGTs higher...at wide open throttle mainly though. When just towing with a reasonable gear selected even in some decent grades, you shouldn't be going too high though. Your numbers seem about right, if you ask me. 1300* isn't anything to worry about, ESPECIALLY if you are towing 19k.
