I haven't heard of people being able to tune in power to the TC/Stabilitrac systems...I have read they've turned the torque-management down quite a bit....
The magic of the ZL1's chassis control is the PTM software; which is a separate system that makes use of the TC, Stabilitrac, and MR systems in harmony to keep the driver in complete control. Since PTM is not available on an SS, I don't think there is any way to get that same level of computer control.
