Changed my mind on mods

I keep changing my mind about mods (I am not sure if my dealership will be a stickler for the whole warranty/mods thing). I bought some window louvers (which i need to install) and I am thinking about some 12" stripes as well. When I bought my Pony, I was the only Windveil Blue around. Since then I have seen 2-3 around NVA and I want mine to stand out. And as fun as the car is already (I am still amazed by how fast my stock V6 is), I am itching for just a little more power... I am thinking about limiting my mods to the MMR CAI I have already purchased, an SCT XCAL2, and a JBA muffler. I will have to "stable" her for the winter (way too much salt on the roads around here), so will probably wait until the spring for the dual exhaust and new headers.

Speaking of the XCAL. I can order one from MMR with the CAI tune already on it. My question is will I need a shop to do the tunes or is it self-explanatory enough that i can "plug and play?"
