Hi guys Well i've found the S3 i've been looking for and i'm picking it up 2moro. 57 plate S3 in white (pics below) with completely standard engine. This i where i need your advice. What mods do i need to get the car pushing 300 bhp+ ? And can anyone recommend the best tuners out there to do the work. I'm based in south wales so ideally as close to me a poss but i am willing to travel.
