Na man at full throttle there is definitely a performance difference. The car feels much more aggressive at low-mid revs, even when the car has complete traction on a good surface.
My best guess is that VSC limits the electronic throttle to some extend, to avoid wheel slips and bad traction on poor road surfaces. Not sure if VSC is pre-mapped to do that, or if the sensors are too sensitive picking up even the slightest wheel speed difference, but I'm very certain something is going on there.
