    So far as I know, Hypertech is the only company that's got a programmer out for 2012-up 3.6L Pentastar motors and that just came out. Needless to say, I don't think you'll be finding too many people with one yet. We are running an AIRAID cold air intake and Dynomax exhaust and like both but, you've got to know that the performance gains on them are minimal at best with any thing like this unless you run headers as well and, I don't think there's anything really out for a 2012-Up yet. Having said that, I think you will find that your motor is more than peppy as is.

    Give the programmers another year or so. An intake and exhaust is about all the really is out for the 3.6l. Headers will never exist because the exhaust manifold is intergraded to the cylinder head. From what I have read and know about this engine is that it was built and designed with forced induction in mind. So soon I would think we will start seeing turbos and superchargers for them. Dont be surprised to see H.P. numbers in the 400+ range when they do.
    never name your jeep after a women, eventually you will want to flip it over to take a look at the under carriage.

    Yeah, "manifolds" are machined or casted with the block. Not sure why but I'm sure the aftermarket will be awesome within the next year or two.
