I'm new to this forum so first of all, hello
I have just bought my first S3 so i am looking for a bit of advice on tuning, I live in south London and the closest mapping place to me is Swiss tuning which is a Celtic tuning dealer.
Has anyone had a remap by either of these and if so what do you think? They claim to get my car to 270bhp, im guessing this is slightly optimistic?
Also, they say i dont have to do anything to the car before the remap, although advise me to buy a panel filter, is there anything else i should do before i get a remap?
Thanks in advance,
