Ok I go outside right now and take the vacume line off of my bbv right now and go drive it it will do the same thing.by taking the vacume line off you are doing the same thing. It's not goinh to make full boost even if you're bbv was good if you take the vacume line off.
If you hook all the vacume lines up like they are suppose to go and can spray underneath the bbv and the engine rpm changes then you have a vacume leak at the rubber boot that the rod rides on.
I have an extra one that I just got. If you pay shipping then i'll give it to ya for free.
