i had mine remapped by celtic, turned on all the warning lights and disabled stop start. the guy said they will just go away when the ecu learns the new map. suprise suprise they didnt. had to take it back to alfa and they had to reset the ecu, luckily asking no questions... the only good thing i can say good about them is that they gave me a refund. Also he said it normaly happened...
If you done a search on google or on here im sure you would find the post.
More recently i had mine done by monza sports tuning. search for it and you can read it.
Check autolusso also they had a few options open, however never personaly used, alot of people have good things to say about them
