Possible Boost Leak?

[Destero]

Hello,

I had a cracked waterline under my rb26 intake plenum. I removed the intake plenum to get to the hose and decided to send it into a workshop to finish the rest of the work.

They replaced all my water lines and re attached my intake plenum with new gaskets. The car was sitting around for a good 6 months before the car was finally on the road running again, however since i have received the car back the turbo(gt3582r) has been spooling about 5000rpm instead of the usual 3500 and doesn't seems to be pulling as hard as it was.

Does the symptoms of the late spooling and less power indicate a boost leak and could there be a problem with the intake manifold not sealing properly causing it?

Yeah, sure. It could also be that the boost controller wasn't put back on properly, or maybe the wastegate is stuck open, or the classic rag in the intercooler pipe. And so on.

It's always pressure test time after messing with intake stuff!
