I remove it and put manual boost controler, and I think there is boost comming faster after put mbc. someone told me that can be possible because amal is pulsating device ...

but I also go check my fuel mixure on boost before remove amal. I know that in summer amal reducing boost to 0.3 bar , from time to time, so amal isnt bad to have. But if you are sure that you have good conditions (good fuel mixure, normal intake temp) put manual boost controler. I have it in car, nice thing it is.

edit: amal can late and send signal after knock BUT it low down boost and prevent knocking.
