Bluefin is an option but not the best option and although it will get you more performance from your engine, it won't get all of it.

The above company is a dealer for Motorsport Developments who remapped my friends TDCi 115ps Mondeo and afterwards it pulled all the way to 140+mph and would regularly see 60mpg when cruising. The map was perfect and it was so smooth in every gear.
When remapped it pulled on a focus ST170 and once on the motorway we had pulled a considerable distance on it. Motorsport Developments are possibly the best remapping specialists in the UK. I guarantee you if you go to the above dealer, you will not be disappointed.
