I just got my e-bay type rs bov in the mail. I am going to put it on after work Friday. I see Greddy has a tech page on the install. I was wondering if there are any big differances in the knock offs and real ones as far as instal and tuning goes,or anything else I should know before begining my next adventure in boosting. Hope everone has a good time at the East Gathering.Thanks Rocky.
