This is a tough question. Especially with so little details known about the 6.7 life at this point. Everybody does extensive R&D, but to assume it's supreme to all else is somewhat gullible in my opinion. Yes, extensive R&D goes into the development, but there is a ceiling of cost that must be met. Even for a $70,000 truck I suppose.
For longevity purposes, IMHO, I would delete everything generating those high EGT's. Be it through programming, or physical deletion, I would get rid of it. Heat is the enemy to all engines, and those type of temps cannot possibly allow a modern diesel engine to last as long as say a 7.3L, which I have regularly seen with 800k miles on the ticker.
As far as performance tuning, I could live with or without it. And yes, my answer would be the same for a Chevy. I wouldn't buy a Dodge. (I don't think they're junk, I just feel like the Duramax and the Powerstroke are better products.) FWIW, I think it's just ignorant to validate the quality of your favorite product, by saying the competing product is garbage. Because then, how good is your product, if it's better, just because the other is a pile of rolling garbage.....??? So I would have to say yes, my answer would be the same for any of the three diesel huffing powerhouses. I mean seriously, 20,000 lbs of towing capacity? That's a lot truck.
