iam having to disconect the vac pipe off it to get any boost out of it,its running fine and boosting to near the end of the white when its reconected it feels flat as hell lol all the vac lines have bin replaced and double cheacked could it be a faulty acuator as ive tried another and that the same

[p fandango]

could be a faulty BCS (boost control solenoid), they do get old & fail

i was thinking that but ive got mbc on it so thought it wud sort of bypass the mbs

tighten the actuator ajustable bar mate its proberly too loose mate.what mbc you using mate .you could be unlucky that both your mbc and bcs are nackered
