I wrote to the factory after Adrian's post and had a reply from Mark Evans. His comments were as follows:
1. The company has finished developing the mod and are happy with the results. 2. Only issue they've had is that the spontaneous fuel reading (displayed as a bar) no longer works. 3. Your dealer can fit the upgrade. 4. BHP increases to 300bhp from 285bhp. 5. Price £1,779 + VAT. 6. 320bhp available with a new flywheel for a further £1,415 + VAT 7. This is an upgrade - no contribution from the company under warranty.
I guess you also need to check with your insurance company.
Still thinking about whether to go for it. I'll certainly wait until my Roadster is fully run in and some more to see how the Rev hang issue affects me at full performance. I'd be really interested in the views of anyone who's had it done.
