for once it seems only i kno this from xperience...his car is auto like mine...so vented is going to kick your ass unless you dont plan on passing the speed limit....I told you I had a type RS and it sounded sick, but our cars cant take that seeing as we cant switch gears when we want. I was doing 120 on 75 one day, and as i came up on traffic i decided id slow down...release the throttle and my car went crazy it started bogging down like crazy and i had to pull over to let the bov close properly. i kno you dont wanna have to do that everytime you go fast and decide to slow down...1g bov is what i have now and i havent got any complaints. Except I still sound like a bird going down the street...A big ass bird!!
