Personally ..... no
I had to call bluefin over a number of times because of and issue which they said my cars the issue even though i knew at this point 2 other people at same time had that issue so I ended up taking it off and not even using it and when I put car back to standard it gave me a standard map on car that was dated 2012! When I went to revo they had to update cars map before putting my revo stage 1 on as they said it was out dated and had a dip in performance and showed me on dyno etc plus due to the torque being so low it chews your synchro. . . Now I know synchros on these cars are weak but just happens to be after map install and it went on a motorway...... and I dont rag my car etc a take good care of it and was surprised as it was onway back from ford fair 2016 then talking to a few people on FB mk7 parts page I realised I wasn't alone and after speaking to me they had exact same issues with bluefin from fuel pump giving out too much pressure and going to limp mode, to dip in standard map and synchros going because of torque I am sure @M4RC could tell you about his issues with bluefin also and he got refund because if it.......
This is from my personal experience and me being me digging around to find out in not only one but again just my opinion
I am sure alot of people and using bluefin fine with no mods to minimal mods.
