Ya chips are really a thing of the past and even then they weren't that great.
The handheld tuners are nice since all you really have to do is plug it in and upload the tune.
American Muscle offers decent tunes for v6's and GT's. With the custom option, you get 3 custom tunes and free tunes for life. Really nice if you plan on modding the car more afterwards.
