Found out what it was it was my manifold. As someone sold me a crap one where the bolt threads where damaged I had to make do with it. Between the turbo and manifold it wasn't a close fit so when I would put my foot down it was blowing from there. I would check yours as I did find a small hole in my Intercooler pipe but that ain't causing it. Got a good manifold on now and the car feels way better then it ever has :)
