2008 BMW 3 Series 335i 2dr Coupe (3.0L 6cyl Turbo 6M)
Edmunds alludes, in its full test, to the potential for aftermarket chips to greatly improve the performance of this car. I can attest to this, having installed Dinan performance software about a week after delivery of the car. My car pulls extremely strong, especially north of 3000 rpm. Plus, Dinan matches BMW's 4/50 powertrain warranty. I love this car.
