Hi Corey,
The 6.0 is running great especially since the addition of the GRYPHON. We got 16-16.2 mpg running 75-80 mph on economy mode, on our way to Michigan over Thanksgiving. We were impressed with those #'s considering the size of my truck with that wheel/ tire combo. So once again thank you!
One addition to the GRYPHON for the 6.0's I would like to see would be the ability to change the torque converter settings like we could on the F150's. Or is there a reason we are incapable of doing so?
