Loud Noise identification - Loud rushing or Sucking Air

[Jbeatbreaze]

Just purchased my 2012 Sonic LTZ 1.4 Turbo Auto

Replaced turbo and works great...

Problem:

Extremely loud air blowing or sucking like a wet vac... Don't know if I have a collapsing hose or what...

Only happens when driving and Turbo kicks in...

Aftermarket air intake on it?

You will hear more turbo noises with one. The stock intake has baffles that reduce the noise. Any CEL ?

All stock

Codes for a couple small issues with o2

So I would start there. Check the air intake piping for any small leaks and the flex pipe down before the second cat

Still figuring it out...

Will be changing my air temp/bar sensor tomorrow or Monday will check that area while I am at it...

Almost sound like ox/cel torch
