Just thought I would chime in...
I have a 2011 335D that is tuned and deleted (egr, dpf, scr), and I absolutely love it! Probably around 315-330hp at the wheels, and I can get nearly 40 mpgs on the highway. Once you get the emissions crap taken care of, the car is actually pretty solid. There is an ever growing number of enthusiasts over on e90post.com, and vendors are constantly pushing new products. Bimmer Performance Center in Raleigh, NC makes some solid tunes for the M57.
