Here is some pic of my pre-turbo intake piping. One observation i made is that the EVO bov ive been using is so stiff i cant push the valve open with my thumb.
Does this need to be a softer?
I have an older style HKS SSV Bov that vents to atmosphere im considering testing also. Its adjustable so might help and at the moment any change to this gives me a lead to how to cure it.
