Cheers, had a look over the boost pipes but couldn't see anything. Might try the maf and see,thanks. I figured it's not turbo related as I was driving it earlier in 5th on the motorway and the dead spot at 3k rpm seemed to be gone. And then later it came back but it's higher in the revs now..? So it must be something small.
