ok ty for your help .... hmmm if i have a 10 psi pulley i should get 10 psi at or around redline shouldn't i?...... it is stock except for the pulley and a 2 1/2" twin catback ex would the ex be affecting the boost ? i have been searching the forums looking for the how to to fix it found it a week ago but cant find it now i know you plug a hose off and put a filter on the actuator but cant remembe which hoses any help would be appreciated
i'd expect/think it would get near 10psi if mine did, not 100% sure....just check all ya vac lines, check ya accurator's working properly, shutting fully and the diaphram's inside its not leaking, check ya belts clean and tight and not slipping..
the exhaust might help it drop a tinny bit of boost, i know better rockers , ported heads, cam, extractors, ect all help drop the boost, the better ya motor is and flows the less boost you'll see on the gauge.
