hey everyone recently had a miss and took it in to get fixed. thats all taken care of. turns out it was an icm. but thats not the problem.. the problem is now whenever the car hits a certain rpm under acceleration it makes a strange low sort of moan.. not too great of a description i know. i have a video ill post but im not too sure if youll be able to hear it. its near the end under the engine noise. car still has plenty of power and it holds boost im pretty sure(no boost gauge) any help or direction would be great! thanks

Bad diverter valve(s)?

But would it hold boost if they were bad?
