I'd get a programmer, like the DiabloSport Predator or InTune, get in touch with Johann at DSP and fill him in on the engine specs. He can put together a base tune, email it to you, you load it on the tuner then plug the programmer into the truck and load it.
Run the truck and log what parameters Johann asks for, then email him those logs and he will modify the tune.
Easy enough. Just call them when you are ready and have a tuner in hand.
