I've finally got round to fitting the bumper, and as one of you said, it was the fmic that offset it too much, I've now pushed the fmic back as far as possible and I have also had to cut a chunk of the bumper off (nothing that can be seen from the outside) it's still sitting a bit offset but I'll have to put up with it for now because it looks like my intercooler is wider than the normal one everyone fits.
