    So i've got an 04 wrx stage 2, 40K. In any gear, when i get on the throttle as soon as i get to full boost this horrible noise starts, hard to describe but it sort of a whining, stuttering, whistling noise, louder than the turbo. Coming from under the hood, cant really tell which side. Sort of a mid pitch (dont know if that really makes sense, not really high, not really low) Soon as i let off, noise is gone, only hear it at close to or at full boost. I know that is kind of a vague description but its hard to find words to describe noises. If anyone lives in or around the Bloomington area and might be willing to go for a spin and help diagnose that would be awesome, otherwise any insight would be appreciated. Please let me know if any additional information i could supply would help.
    Thanks in advance,
    Chase

    Sounds like an exhaust leak to me.

    My guess is a boost leak. No fun.

    Sounds like a pre turbo leak, at work we call them crow cars.

    Although I didn't rip into it, I took it for a test drive after work and it's nothing obvious.
