Standard feature or something you had to rig up? If you had to do it, how easy was it?

+1. Go with the Cobb. No piggyback to install and un-install every time you go to the dealer. Go to E90.Post and read all of the reviews on the Cobb. It is a huge hit on the 335i. I am considering one myself. I was originally going to go with the GIAC flash which is awesome as well, however you have to take your car to a GIAC dealer to have it flashed. The Cobb unit does same thing except you do it yourself at home. That way you can install and un-install the flash at your convenience.
