Behaves weird when in pitbox

[Simfreak]

Hi, i installed irffb2022 and i use the irffb 720hz profile (i don't use VJOY), problem is that when the car is in the pitbox the wheel starts turning right and keeps doing that so it basically keeps hitting the bumpstop constantly, also when the car is stopped after i exit pitbox wheel keeps turning right. In general it acts weird when car is stopped... Any solution?

also i have noticed that even when i set FFB to 100nm which is basically minimum force it still is quite heavy, it's like 100nm in irffb is like 3-4nm in actual power..
