Need For Speed PS Problem using XBOX 360 Wireless Gamepad on P.C./ Need Help!!!

I have the Microsoft Wireless USB dongle and a XBOX 360 wireless game pad. I am trying to play NFS ps and am having some issues. When using my left analog stick to steer it is oversensitive. Basically what happens is, When the race starts things are fine until I touch the left analog stick. Once I touch it to steer then I can never get straight again. I have tried getting a Suspension upgrade to loosen the steering Ratio to loose, It helps a little bit, But when your going 200MPH you can't have your car swerving by itself. It is like there is no Dead Zone at all. Any and all movement is registered from the left analog stick and it is impossible to drive in a straight line. I have sent my concerns to the EA official support site. They basically are saying that there is a issue with a Background task or something. But that is not it. I have followed all there trouble shooting tips and nothing has helped. There is no Dead Zone, So what can a guy do? I see that other people are having the same issue using a 360 wireless Game-pad and this game. And no one seems to have an answer. So I am coming here to hopefully get some help. Does anybody have a suggestion to make my left Analog stick not so sensitive??Someone must have a answer or suggestion? Thanx.
