The Supersport and Esseesse 180 maps are applied at the dealer, but these can only be applied after receiving the file from Abarth, using a specific machine and onto a matched car.. Unfortunately you can't just buy one

As for remaps - Angel can do live maps although most appear to be stock maps applied without the use of a rolling road/wideband to check everything is ok. TMC are in Ireland so a bit of a trek for most.
You could opt for a TMC tuning box; you'll achieve somewhere between 180 & 190bhp with one of those.
