This may be a placebo effect, but I feel I get a little better response and driveability when I put my Brembo package car into advance track sport mode. Hold brake pedal down and tap button twice. Brembo cars have some tweaks in the ECM so I don't know if that makes any difference in this situation.
It doesn't do anything. There is only one set of throttle tables. 2015s with selectable driving modes have multiple tables but the 2011-2014s don't.
