I'm so pissed!!! I just installed my new ported, non-sequential turbos and I'm still getting an air pump/goose sound at full boost. Seems like it's slowing my car down when that noise starts but maybe it's just me. Anyone know what the hell this noise is? I have no air pump so I know it's not that. What's the best way to look for a boost leak?

 

it sounds like a problem that i had. i found it to be a problem with my factory intake pipes and the outlet to the intercooler that i have. also, if your air pump is removed, make sure that the flange plates that are needed for the blocking of the un-needed lines on the back of the manifold were taken care of. if not, you will have boost bleed. it should not be too hard b/c you have about a third of the original vacuum/boost lines that were with the original sequential set-up.
