Good morning AquaTune, Man, I tell you what, this AquaThrust system is unreal!!! Darn near scary! I'm calling you as I'm driving down the highway and this thing is just taking off on it's own. Just goin'. I'm almost on people's tails before I even realize it and am having to put my brakes on. This thing flat puts you back in your seat. Love this system, talk to you later.
