VE/VF imo will always be limited for quick 60's imo due to the ESP system still lurking in the background.
Turning off traction control does not remove it's capacity to limit throttle opening on hard launches on the auto's. Have logged a few cars on slicks where the throttle position has a drop off from 100% opening. Nothing to do with trans torque limiting, comes back to the steering angle sensor and yaw/g sensor.
