As Jeremy said, we can convert your 6.0L programmer to a 6.4L. If you have not taken the DPF off, it would be $100 to change the firmware and provide you with a new dash pod. If you would like the racing option, I can e-mail you a copy of the disclaimer for us to keep on file. The total charge would be $250. In either case, you can simply fill out a shipping form (on the ORDERING page of the website) and write us a note as to what you'd like (it's a rare request, so we don't have a designated order form for it). Include it in the box with your programmer and send it this way. :o)
