Fuel cut

So im on my way home from work and punched the gas it was fine until I herd a pop and the fuel cut. now it won't let me boost over 5 psi and the bov is 3 times louder I can't see anything abnormal and it seams to run fine other than that. Any ideas?

No CEL's came on
My car is stock other than suspension work and a turbo back.

Sounds like you ruptured a hose or a gasket failed, something like that. Have you checked the BOV for leaks?

Thats what I was thinking the car idols fine and there isn't any vacume leaks. How do you check the BPV?

Some leaks will only occur at pressure. If you are saying that you can't get past 5psi I would imagine your leak opens enough for air to escape at 5psi. You should do a pressure test.

That makes sence I'll have to check it tonight thanks. How exactly would I go about doing a pressure check on that?
