Duffs, some good advice by a few people here. the best thing to do is contact Austec, explain the situation and ask for a rough estimate of how much it's likely to cost to fix.
The £1000 I was quoted was directly by Paul and on the basis that I needed a full session reprogramming fuel and ignition maps plus burning chips.
My other experience was with my Caterham that needed 8 hrs on the rollers to fully map to perfection and although that was a good 3 years ago, it was still about £600 (cash).
A rolling road session to detect a fault might be rather different to on e where you are searching for the last 1bhp and therefore you may well find that it's less expensive than we fear.
Would be good to hear the outcome!
