Tutorial on using the SCT X3 tuner to tune your car. My car is a 2008 Mercury Sable Premier with Ford's 3.5L DOHC iVCT Naturally Aspirated V6 Motor.
This tune slightly increases power on 93 octane gas but really helps for drivability. Throttle response and shifting is so much better after the tune. Feels like a sports car.
