Sorry if this is a bit irrelevant to the whole discussion but I can't seem to find an answer anywhere. I came from a subaru and whenever you got a BOV, you needed to get tuned for it otherwise it would act quite silly.
Do you also need a tune for a BOV on our cars? Apologize if the question is dumb.
