Interestingly, the power/torque chart in the S58 technical document shows values for the S58 up to 7,500rpm. All that being said, BMW certainly had their reasons to keep redline at 7,200rpm for the 6MT.

I understand that the torque/hp graph clearly proofs that the the boost is gone at 7200rpm. Increasing redline a few hundred rpm will probably (alsmost certainly) make the car slower.
