I did some calling around some tuning companies recently and it looks like we will be able to map the 3.0TDi up to around 290bhp and 560nm torque without any problems. This won't even add any stress to the engine, fully comply with tolerances and shouldn't even effect fuel efficiency by an noticeable margin. The remap will allow access to all that torque over a broader rev range making the car more drivable and decrease the 0-60 time by around .4 of a second. 3.0TDi at around 5.4 secs sounds good to me!
There are several companies that have looked into it for me. Charges will range from between £375 for a generic call out service to £600 for a rolling road custom remap and tune.
If anyone wants any more info let me know and I'll be happy to share what details I have.
