Whistling noise under boost?

[gobeli67]

Ok so i put on a now exhaust housing and actuator on my turbo an now is whistles when its under boost. It never did this before but i think my old actuator was shot. Is this normal or is something wrong. The car runs fine and still pulls like a champ.

does it sound like a whistle or your turbo spooling up?

Sounds like a boost leak...

Its a whistle. Ill check my j-pipe gasket tomorrow, thats probably it because i have reused it like 10 times and just keep putting gasket dressing on it

sounds like you need to do a boost leak test
