I went with the PCIII. The main reason was they had a map available on their website for the exact combination of exhaust and AC that I have. I also like the fact that you can hook it up to a directly and tune it. I've actually stored the USB cable under the seat so I can just reach under and pull it out to make an changes. The PC interface is very intuitive and easy to use.
