I also have the BlueDriver, but it doesn't support a whole lot of params for the live data. I emailed the BlueDriver support team the day after I got my delivered from Amazon to ask about it, and they SAY they're going to add support for GM Enhanced parameters, but who knows if they really will. Other than that, it's a pretty neat tool, and like smg267 said, it'll do all B-class, C-class and P-class codes, which is hard to find for any scan tool under a few hundred bucks.
