That's why they regulate speed rather than torque.
Torque monitoring (alone) is not optimal as the slightest bump in the road will generate a variance in how much torque you can apply.
By keeping the speed stable a momentary loss of traction will not cause a slipping wheel.
TC works by bringing the speed of the wheel back in line with the others.
No need for that if the speed of all wheels is the same to begin with.
As the weight transfers from the front to the back the front wheels get less grip while the rears get more. But all of them need to turn at the same speed.
That said, if they overdo the speed buildup all 4 wheels will lose grip and the thing does a 4 wheel burnout.
