Cant wait til it comes out for all CR trucks. No speed limiter and 4k would be great. This may very well open up a whole new chapter for the CR Cummins. One question: does the TC/VB have to be built or tuned specifically for a truck rappin out to 4k? I mean, with a regular TC/VB, would it still shift at about 2900-3000, and then pull 4k on the top end, or would it wind up to 4 in all gears??

The springs on these trucks are weak to begin with so I am sure they uped the springs. Even with stock rev and stock springs you can kiss a piston in the right situation. Now I think with a cople upgrades you can safely turn 4000+ rpm.
