Cheers guys. I only have one graph that states 197, it doesn't say wheels or flywheel so I will assume flywheel til I have her dyno'd myself. Also, Zeldoz, 197 at the wheels would be 230bhp with a 17% transmission loss. A 20% transmission loss would result in 236 at the fly, but 20% is a lot! I didn't know mappers use 20% as a guide. I've just given her an oil and filter changed and fitted an ID-Workz magnetic sump plug while I was at it. Mileage reads 122,187 for future reference.
