Well here are some updates:

I have mopped my murky xenon headlights and they look fab! Will get pics up on my photo album.

Had the car remapped today by EU Tuning. What can I say...it was well worth it! It's made the throttle more responsive and in every gear the flat spot has gone.
It's currently running at 180bhp with the remap, exhaust and k&n panel filter with auto air deflector. Well happy with that as it was probs running well below the claimed 170 mark! 😄
