The reason the S63 engine with the ZF 8HP76 is limited to only 553 lb. ft. of torque is because BMW is to frugal to use the stronger ZF 8HP95 trans like the Trackhawk uses. BMW uses it in the RR models.
Then they could allow the torque to go up to 664 lb. ft. which I'm sure the S63 is capable of obtaining.
