I can't see how turning the TCS off makes the trans work better but I don't doubt that it's occurring.
There could also be a torque management logic in play when the TCS is active. We know the car has torque vectoring, which is just a way of using the ABS to control torque steer. However, in most electronic throttle cars, there is a torque managment system that will reduce the throttle plate angle as well as using the ABS to keep wheelspin to a minimum. With the TCS off, these electronic nannies are reduced/defeated and the DCT logic is not competing with the TCS and torque management systems.
I honestly have never turned the TCS off in my MT car. I'm going to try that and see if some of the hesitation I fell is reduced as well. There is a TSB out for the MT's as well, guys report that it wakes up the throttle response. I'm thinking it too backs off the torque management nanny.
