By the looks of it, what we've learnt here is:
(a) they're capable of writing maps to deliver roughly what they quote
(b) their customer service is excellent
(c) they need to do some serious housekeeping on their servers, audit everything and importantly do it right first time (quite rightly pointed out by T_T) For existing users ensure the right map is there for each car and then contact every Bluefin owner and get them to do a remote update.
They should be more pro-active in the latter, as it seems they're only responding when questioned - but what people need to do is go and speak to them if they have a problem like the OP.
