From what I gather, the consensus on Bluefin/Superchips TFSI maps is that at Stage 1 they're ok, but their 2/2+ maps seem to have a bit of a bad cred.
There was a thread a long, long time ago where a Stage 2/2+ Bluefin car was data logged, and it didn't sound great. Think along the lines of big boost spikes etc.
If you're happy with how the car now drives, and all the necessaries are in check - boost, timing, AFR - then happy days :)
