Does anyone know how to set Greddy Profec B?

My children play my setting, now out.
Currently when boost to 0.6 bar, car will junking or A/F run as high as 17:1
. The AF gauge show jumping 14 ~ 17 then suddenly back ok to 12:1

If OFF Profec B, Smooth drive. But low boost level.

Try lowering your boost pressure 1% by 1% and boost and see if the car is still jerking.
