If someone can explain to me how to properly adjust the Turbosmart Dual Port BOV, what hard and soft refers to, and where it should be set for optimal performance without the car running rich, that would be awesome. Thanks.
 
the turbosmart valve should be set to one quarter inch space to begin with. your ecu also needs to be reset. then from that you go harder to hold more spring preassure for harder driving, and softer for normal smoother shifts, however going too soft can cause stall and and turbo flutter, going too hard will bring backfires and rougher shifting but is obviously better for track and spirited driving. dont go all the way hard and dont go all the way soft otherwise its a jack in the box.
