I have a "problem" with the acceleration and top speed of the GT500. Im always slower than the AI, regardless of the track im racing: Sebring, Malaysia, Salzburgring, Road America, as soon as i exit a corner with a higer speed than AI which is behind me, that same AI looses some space when we exited the corner but catches me like im standing still on the straight. Nothing i can do. I tried to (re)-calibrate the gears but whatever i do it seems im just short on raw power. Can anybody help me?
