I just replaced my 4 yr old stock BOV. I couldn't boost past 22-23 psi. Picked up a new Samco unit from AMS. My car is a different animal now. Lightning boost response. Better thottle response. Even shifts smoother. I can't figure out how such a relatively inexpensive part makes such a night and day difference. I'll head back to the track for the real test. Looking for lucky 11's.
