Agreed. Redline on the N54 is a bad idea, power drops off dramatically after 6000 rpm. Just drive it and find out. It bugs me no end that kick down revs way past where usable power ends, you can feel the thump in your back as the turbos, at full tilt, are then used for the next gear change. If you want maximum acceleration, its sport mode, manual DCT shifting and make sure you change up very shortly after 6000rpm each time.
