Custom tunes from vivian or innovative diesel.
You can get any of their tunes for your type of truck and they will all be safe. But I am not sure about innovative Xrace, I feel that is a little rough on the trans.
For innovative, the "Street" tune will be good if you do not want to chance it. it gives you power, mpg, and good tuning for the trans. But there are tunes in between "street" and "Xrace" that many use and like and are safe.
If you do not want the engine tuning, just get a trans tune. But you really should get some kind of tune that does both the eng and trans. One reason is that the custom tune can turn off your egr valve. That is a huge +.
For innovative diesel, put in an order for what ever tune(s) that you want, Eric will email you a few days later asking for how you want your tunes, mods on the truck and what kind of flash you have. Then in a few days he will email you your tunes, load them from the sct program onto the sct, then on to the truck. it is a straight forward process
