Thanks to the OP as I just updated my 2008 e90 6MT to 46.6. I've never had an update and the initial software was from 12/2007. I can feel more torque from 3-5k. The car definitely runs smoother which isn't all good since I love to back off the throttle to hear backfire and burbles. I can't get it to do this now. The dealer charged 1.5 hours of labor. So far I'm very happy with this mod. I will report back after a few hundred miles.
