I am using a Neo SE Joytech controller and when I attempt to go in a straight line the car veers to the left. I have went in to the controls and centered the axis and everything. Am I doing anything wrong? Any help is greatly appreciated!! Thanks!!!

Sounds like there's still a calibration issue to me. Or the need for a deadzone.

could you explain to me what a deadzone is and how I would go about adjusting this?

dead zone is a zone in the center that the stick doesn't affect the game.
