the ports inbetween the throttle plate for air bypass need to be opened and joined up . and the std valve needs to be modified to run any decent boost , i.e the end of the std valve gets removed and has a conicle taper bush like a top hat put in it instead of the fixed air bypass , the std parts can me hand modified to run an effective als system , just not producing massive boost thats all !!
