    I read in the new Car and Driver that overboost is available only in 3rd to 6th gears? My butt dyno seems to agree, does anyone know for sure? Does this change with ESC in comp mode or disabled?

    Hmm... Car and Driver says "to boost midrange power in gears three through six". However the description in the ST supplement says improved performance for passing and vehicle launch. You're not going to launch in third gear. at least not on purpose

    Your ST vehicle offers a period of
    additional torque delivery referred to as
    overboost or overtorque. This feature of
    the engine calibration broadens the RPM
    range of the peak torque curve. This gives
    improved performance during maneuvers
    such as passing and vehicle launch.
