Hi folks. Please help. Just bought my 07 cx7. When I have radio off I can hear a hiss coming from engine when accelerating. Is this normal turbo sound? Or is it something wrong? I don't remember hearing it the first week of owning the vehicle. Now I notice it when radio is off. And I usually have radio off all the time. Pleae anyone have a suggestion?
 
Could be a boost leak. Check all of your pipes/hoses/connections. Could also be your BPV, it is plastic and can leak
