    I've seen several comments about the latest software version 4.0 update increasing performance? Does anyone have any hard data on this? Did the car get even more ridiculously faster than it was before? 0-60 times better or squeeze out more torque perhaps?

    No, it changed the throttle mapping to make the car "more responsive". If you have the pedal to the floor, before and after the modification, I'd expect the exact same result.

    It fixed a dead zone in the beginning of pedal movement. Now it starts to accelerate earlier in motion.
