My uncle has 335i with the JB4 upgrade and it is unbelievably fast. The JuiceBox upgrade is $500 and makes the 335's faster than M3's. Not only that it's not detectable by the dealership so no warranty void and it comes with 3 tuning settings.

That alone is one of the reasons I want to own one of the BMW's with the N54 engine. It also has an amazingly flat torque curve.

But 100 HP for $500!!!!
