Bluefin quote figures of around 310bhp on their website,and to get the maximum from this you would need a CAI and exhaust upgrade.
I know you already have their software on your car,but you might be better off looking at a Stg2+ upgrade and a custom remap,from someone like Rick at Unicorn.
That would easily take you to 360bhp,and get the maximum from your car without the expense of a hybrid or BT kit.
