ST, I appreciated all of the information that you have provided with this thread. We picked up our 08 6400 in 2017 and have been debating a re-power since our first trip to Colorado that year. I have looked at the Hypermax but with the limited torque capability of the tranny I am a little leery.

Have you been able to get yours out on the road since the install and if so what kind of difference did it make; performance and fuel economy wise?

Have you done any other upgrades since you picked yours up. We are seriously thinking of installing a Kelderman rear air suspension to help with the ride.

We are still trying to figure out what works and doesn't so if anyone has any good tips it would be greatly appreciated.
