you mean downshifting right? backward is upshift forward is downshift."Put the car into S5 mode. Turn off the DSC and then that'll unlock S6. Put the car in S6, foot on the brake, push the shifter forward like you're upshifting and hold it there until the checkered flag appears on the gear indicator screen. Pedal to the floor and let go of the shifter when u want to launch. Keep it 100% pinned and it'll shift at redline until you get scared and/or let off. U can adjust the launch rpms on the cruise control stalk."
