Well that's good to know that Rocketchip is still doing it. I think some places have stopped advertising but might still tunes if you email them. Seems most of them require you to send in the ECU but I have seen a few that can be done via OBD2 port. I probably won't start shopping for a few months, or even until next spring, so I am interested to see how your experience goes! I still have some other issues to sort out first.
