I drove a new 11 with a 6.7 and it was fast but running 37's turns a stock motor into a dog, that new 6.7 would need a tuner just to get back up to stock power levels. Still though, 400hp is nothing to sneeze at and I think if the tuned 7.3 is putting out 400 hp then yes I can see the 7.3 tuner running all over a stock 6.7 with 37's.

I have a 10 6.4 with 35's and 4 1/2 inch lift and I can say you loose a lot of power going to big tires and lift. I also lost 1 mpg

Sorry bro, but you've got to have a lot more than a good tune in a 7.3 to run down a 6.7, even on big tires.

I think you guys are forgetting that a 6.7 is making 400hp at the crank, not the wheels. That puts it at similar power levels to a tuned 7.3 at the wheels... then add big tires to the 6.7 and it's not hard to believe that a tuned 7.3 would walk away...
