It'll wake the car up some, maybe 15-20 hp gain there, most of it coming from the tuner. CAI's typically don't add a whole lot, the factory setup is pretty good. The resonator deletes will definitely make it louder. You'll probably want to turn MDS off or at least see how it sounds when MDS kicks in with the resonator deletes, might sound kind of silly with just 4 cylinders running.

Another popular/cheap/simple mod to do is installing a 180 thermostat and removing the stock factory 203 thermostat. Then lower your fan settings with the tuner. This will help the car run cooler on hot summer days and prevent heatsoak from robbing power. The Jet thermostat I got was $35 or so and I installed it myself in about 30 minutes, very easy to do.

I also bumped the throttle boost up to 20% all the way on my Predator, I'm assuming the new tuners have that feature as well. Now when I hit the gas the car takes off fast. Some people don't like that but I think it's great.

You can take it a step further if you want and get a custom email tune for the car. I did that and it woke it up a little beyond the canned tunes that come on the tuner. You'll need to datalog with a laptop and send the datalogs to the tuner you're working with. After a few revisions and tests you'll have a tune that's made specifically for your car and will have some better fine tuning aspects over a canned tune.

Otherwise, beyond things like that or maybe a front strut/rear strut bar, mods start to get quite expensive on these cars. Supercharger would be cool but prepare to spend $6-8K for one of those.
