Well i am no expert, but i think a basically stock 6.0L is not going to hold up very well to a supercharger and spray. I just think the cylinder pressure would be way to high for a stock bottem end.
Also you will need a hell of a lot more tuning then you will ever get from that hand held tuner. You will probably have to get a custom dyno tune to run the truck at its full potential.
Just my .02
Someone else will probably go more in depth with what else you need.
