T300RS GT FFB issue (keeps centering itself)

[futuco]

i have a g25 and i am suffering from almost the same thing, when the car is stopped the car wheel goes the 900° with no problem but when the car starts moving then virtual wheel goes to the center and when the speed goes high the wheel goes more tho the center even if my real life wheel if full rotated if the car goes above 50 kmp it 100% straight
