"hissing" sound and boost is down but no leaks
I have this "hissing" sound that gets louder with boost. It's been there for a while, thought it came from the intake. Changed my hoses and got a leak check but sound is still there, even replaced the BOV. Now boost is down to .9bar and Dynojet baseline run is 240 from 298. Friend said turbo is toast...appreciate some feedback please.

Thanks, will check. Forgot to mention that a tuner installed a restrictor pill and it was fine for a few months, then started spiking to 1.8 bar after a few trackdays. Took the pill out and it would spike to 1.6bar and settle down to 1.2bar. Then this happened.

he said "leak check" but my hunch is....boost leak test wasnt really done.
your friend is wrong about your turbo "hissing", you shouldnt be taking car advices from him lol. blown turbos will howl like your cars haunted hehe. "hissing" = leaking air. boost leak test will show the location right away.

I wish, all I need is a mongoose to fix LOL.
If a boost leak check means running 2 bar of compressed air from the hot side of the IC to check for leaks, then yes we did a boost leak check.
I took off the intake pipe and checked the turbo impeller, found no play and spin was good. Will probably pull out the whole turbo to check the hot side. Will also try a wastegate swap.
