IMO a tune, like everything else, really depends on you and your goals for the car. If your going to install the H/C/I and be done, go with a chip and let the professionals do it. However, if you are planning to further alter the combo in the future, it might be worth looking into something that allows you to tune the car yourself. The Tweecer R/T is really nice, i'm hopefully going to pick one up in a few months, but it does require a lot of learning before you can really make any significant changes. That doesn't bother me because by then i will really understand what is going on with my motor and thats valuable in itself. The PMS is another tuner you can use that is much more user friendly. It does cost a bit more. There are a lot of other ones out there, but i would decide whether you want to deal with tuning the car yourself first before you decide which tuner you need.
