I am most skeptical, but the bizzare thing to is my Xfire does sound slow on start up when the dang wing goes up! Anybody ever look into this to see exactly what the car was doing to launch its wing? Is this a byproduct of something else or did someone actually figure out how to make a weak battery indicator?
