    Notes: Stage1, Stage2, and Stage3 OTS maps have brake boosting enabled for 2 seconds. You will be able to floor the gas with your foot on the brake to build boost. The timer for the sport button has also been raised to 30 seconds so that you can enjoy the overboost feature for longer. The additions of any other hardware may cause the vehicle to perform poorly.
