Manual 6 speed 2018 gt has progressive super charger. In 1st gear if floored front wheels come up so caution is always employed there. However, if floored in 2nd gear the back end becomes so squirrely you have to let off. I was under the impression mustangs had traction-loc. If so shouldn't this transmit the same power to each rear wheel and prevent the rear end from taking on a life of its own.
