I'd say with about 99% certainty a tune will NOT be required.

the shorties will be worth 10hp MAX. CAI may be more like 15 and the catback probably 5.

Id say 25 to 35 to give you around 450hp stock

I can't imagine any problems running high 12's with a good driver with these mods on an average day.
