Go for the CAI, no tune is required but you'll find it's recommended. Take a look in the performance forums here and you'll see the common mods and summaries of what works best. Most common:
- first order of business, get a catch can
- CAI (BWoody, Arrington, Mopar, etc.)
- tuner (Trinity or InTune)
- Jet 180 t-stat
- custom tune, you'll find a couple members here who'll work with you on it. There are canned tunes on the Trinity or inTune, but custom tunes get the most out of your rig. Big improvement.
For these light mods you'll notice the biggest improvement in the CAI and custom tune.
General summary with exhausts are they don't offer performance gains, they're mostly for sound with these light mods.
