Can this package be installed on an existing car
Hi, i have a 3 month old 2010 e92 M3. I am wondering if there are performance upgrade thru ECU or changing few minor parts on the vehicle, will this option be available as an add on. C63 has a sports package in which a "revised" ECU provides 30 more hp. I could definately use an additional 30hp and 50nm torque, or a second quicker 0-120 mph acceleration.
