just a little fyi, my pops bought the speedtuningUSA flash today, there local to us (4 miles away) said right away he noticed the car drove much smoother and reved more freely. the way he described it made it seem like a anchor was taken out of the trunk. should get better from here on out once the car learns the new SW fully. say what you will about getting what you pay for but a few others have his stuff and have nothing but great things to say.
