I recently bought a 09 and am looking to do some mods this summer. If Anyone can educate me or point me in the right direction on what these tunes are all about. I am very new to this technology and it is alot different then what I am used to. From what I gather you can't even put a cold air intake on these cars without having to do a tune. If someone could break it down for me or just put up some links where I could read about how to input these tunes and where to get them? I appriciate the help and realize that someone else has probably gone over this before.
