What is out there for the N55?
I have a '13 X6 35i on order, should have it within the next 2 weeks. I have the N55 in my 335 now and going into the X6 it will be about a second difference 0-60, I just hope its not noticeable. What is out there to Tune the car other than JB4? I love the way the Injen intake sounds, would it fit? I am not looking to mail out my ECU to get flashed.
