When i give my car 20% throttle while driving it makes a constant turbo whistling noise. Also while tapping the gas from idle it makes the sound but it's more of a squeek. The noise comes from the engine bay. If this is a problem how do I track it down?

 

Did you put a new intake on the car? I put an ebay intake on my car and it does the same things... intakes just do that some times. I don't know about the stock intake though.

 

yeah I have a custom intake and a jeep TB hollowed out to about 57 mm. Itbecame more noticeable after the mods especially the TB but I think its always been there.
