It's great to learn how to tune but do your research first and have someone experienced check you first couple tunes. I've seen some ugly results from people doing their own tunes on BMWs. They are more difficult since they are tuned pretty strong from the factory. A lot tougher than the LS motors, but when people start doing their own tunes for forced induction and end up with holes in pistons. Not trying to talk you out of it because it's nice to be able to do it on your own. An hour on a dyno with an experienced tuner will give you the biggest gain. You can make little tweaks after that.

I've got the BMW software and all I use it for is to change factory settings for windows and stuff like that. I have a local expert that does everything else for me.
