whatd they do to make it worse???

 

most likely a dying turbo... if its really high pitched almost like a supercharger its a dying turbo.

 

I don't know, they just took my car for like an hour and fiddled around with it and it started sounding more noticeable...it stopped for a few days and now it just started back up again today...I wish I could explain the sound better...it sounds like it's coming from the left side of my car though..
