Never had the Bluefin myself, went for Revo stage 1, last December.
Principally because I wanted to just go to a tuner with a rolling road, have the map fitted and know it was installed right.
Personally did not like the idea of paying for something that is pretty much hands on, preferred to leave it to an expert in case of any issues, was worried of having issues with my install with the Superchips Bluefin option.
Just my view. And of course others will love the downloading of maps etc.
As an aside everyone seems to talk of Revo being aggressive etc.
In my very simple/layman's terms the car (Ed30) is fantastic with a Revo map, it just gets down the road very progressively and is brutally fast compared to a standard state of tune.
As lots on here mention a remap is just the start...of the modding slope. Enjoy the journey.
