BOV not actuating.

BOV not actuating.
Just picked up a hatchback that has a b20 turbo setup and the BOV isn't releasing boost pressure causing the turbo to.surge. I've replaced the vac line from the T to the BOV not sure what else I could try to fix the issue any input is appreciated

Re: BOV not actuating.
the tee is your issue, that small line can't supply enough vacuum to run the fpr, wastegate, and bov.
the wastegate needs it's own line, as does the blow off valve. the fpr has relatively low vacuum needs, the wastegate needs the strongest signal so it can operate correctly, same with the bov

my guess is a bad BOV, or a vacuum leak in the line.
P.S. you should never T anything into the line going to the FPR, it will cause inconsistent fuel pressures when manifold pressure is changing, which is basically all the time.
