New software really smoothed out the engine and eliminated some partial throttle hesitation/missing experienced at lower than optimal gear speeds.
That coupled with transmission and diff fluid service makes the car feel buttery smooth.
i also had the new software installed and these fluids changed recently,and had the same positive experience.
