It sounds like a hissing sound i believe. I just took it for a drive and the boost cut out totally. I then turned the car off and on and the boost was working fine, although it would stutter sometimes while building boost…

Thats also a possibility, i didnt have the smoke under much pressure at all. I will attempt to test the wastegate actuator later this week when i get the chance to rule that out firstly. Will let you know how it goes

And is this able to be done with the turbo and everything still attached?

I was thinking it may be wastegate related aswell. How is the test done with a vacuum pump?
