Thrustmaster t300 assymetry turning left

[blay0570]

Hello, I have detected that on my steering wheel thanks to the thrustmaster software when I turn to the right the real turn and the turn that appears on the screen is exactly the same. But when turning left, every time I turn the steering wheel more, the difference between the real turn and the turn that the software detects becomes more evident. For example if I turn the steering wheel 180° to the left, the program detects 170°. But if I turn the same to the right the symmetry is perfect. What should I do?.

But the center point is perfect set it.
