Sounds a daft question but all fabia vrs`s seam to produce more then the 130 stated. So is this true of the 170 as well?

It's more accurate I believe.

I'd expect 170 to 175.  Remap to 200/205.

Mine ran 175 stock at 1500 miles I think. Then on same dyno another CR170 with 12000 miles a year old ran 185, he had baffles out and a K&N panel filter in apart from that stock too.
