Tune is fine. Nothing wrong with a CAI, either to help the flow of air just don't expect higher numbers with one. It's fine if you plan on going with a Boss or CJ intake as you will want more air than the stock box, IMO. But you can always just use a drop-in for better flow, stock.
Bama V2 is worth it and then some, personally. You will love it. Race tune 24/7, btw. You will be fine.
