Btr stage 2 or 3?
BTR stage 2 is a 227/234 .614"/.576" 113+2
BTR stage 3 is a 231/242 .617"/.592" 112+2
For your application the stage 2 is definitely more appropriate and is by no means "small".
You should look at getting a ls6 intake as well before the tune, it will be worth a good chunk of additional with a mid size cam like that (I would venture to say between 15-20hp).

With 4.11 gears, go with the Stage 4 you won't regret it.
I would DEFINITELY go with at the very least an LS6 intake.. ideally a FAST 102 or 90 would work great.
