I have always wanted a "Performance Module/Chip". Jet is one company that a lot of people seem to talk about. It was easy to install and they said i would notice max performance after 200 mile. I just past that and I do notice a difference. is it worth paying over $200 for? I don't think it is. Not when it comes out to $14 per HP. The install took only 5 min. This chip is small so it is not an eye catcher. best part about it is that if something went wrong on my car i can take it out and take my car to the jeep dealer and they won't know i ever had it.
