Boost issues-Stuck BOV?

[ksd9000]

Hello all. Just got done rebuilding the engine and running into some issues. All components are stock except for the 3" turbo back exhaust. No CAT and just a free flow muffler at the end.

The issue I am having is that the intake soft pipe (where it comes out of the right fender well to the 3000 pipe) keeps blowing off when I push it hard. Stock boost gauge shows 8+ psi when this happens. Double checked all vacuum lines and made sure the bypass valve is connected. Looked through the TSRM and didnt see any info on how to test it. It also sounds like there is no pressure relief when I let off the gas after hard acceleration. I can hear the intake charge resonating in the intake after the hard acceleration and let off the pedal.

Maybe I'm not tightening the intake tubes enough, but I dont want to chance it and not have ANY pressure relief if the BOV is not working correctly.

Car is not being driven for street use. Track only. Not that it makes a difference.

Any help is appreciated.....
