Hello, I just bought a 2005 STi a week ago and I have a question.
I was thinking of getting the HKS SSQV BOV. But I read a forum on the HKS BOV and a few said it bad news cause it cause lag to a stock motor. Then some said depend on the setting 50/50 or atmosphere. What the different between the two set up and is the setup in on the BOV itself. Plz reply very concern.
