I just unplugged the connector on my 2009 335i sedan.

No error codes on dash board.

Sound is sweet ! Its not ricey loud, but u can notice the difference ...its a more "classy loud" , if you will.

Also, after mod, i can now hear the "woosh" of the turbos as they spool and that sounds amazing never heard this sound before prior to modding !

I took a short idling vid before / after mod.... ill put this up if u guys want ?
