Corbin I have never heard of a 6.7 windowing the block with a tune only setup... The only trucks I know that do that are the ones running compounds.
The first two that I went back to look at on this site, were compounds.... So I guess the others might or might not be.
The others, I am sure that they were stock fans. Except for one of the ones at my dealership. Its motor was out when I saw it, and it could have been anything. I failed to ask, I merely assumed. I saw the others in person. And my buddies' trucks were stock as well. Both of my buddies ran their truck hard, like they did with their 6.4s, so that undoubtedly did not help matters.
Regardless, I am staying with the 6.4, and keeping an eye on these developments. would like to see more HP, with twins or triples, and fuel, and no window installation...
