That was a very interesting read. The jist of it seems to be that remaps are preferable to tuning boxes because they work directly with the ECU as opposed to tricking the ECU, and therefore put less strain on the engine, injectors, and other supporting engine components. Perhaps somebody more knowledgeable can chime in and make sure I'm getting it right.

In any case, there are only 2 things holding me back from getting a JBD. One is I don't want to risk anything with my warranty. And the other is concern about long term reliability. Many people are running the JBD and are very satisfied, but what worries me is what will happen after 50,000 or more miles of running the car at a greater-than-factory power levels. Perhaps that's not as much of an issue for someone who's on a lease and planning on changing out of the car in a few years, but I plan (and hope) to keep mine for a very long time.
