Just to save you a bit of time ploughing through the search engines I've put my choice of top/recognised tuners for Audi's (VAG), and although originally was aimed at chip tuning encompasses general tuning as well, and does have a focus on the UK market;
Most recognised within the UK:
APR -
www.goapr.co.uk/dealer/index.html - Good maps and well respected, especially in the US. Just released OBD* tuning. Switchable options using cruise control.
REVO-
www.revotechnik.com/uk/ukrevo.html - Good maps, one of the first tuners to offer OBD* tuning in UK. Switchable options using switch (Dongle).
AmD -
www.auto-amd.com - More than just a chip tuner, they are a complete tuner unlike many others. Respect. New one-click system offers another option on tuning, by use of the OBD port.
Jabbasport -
www.jabbasport.com/Audi/Jabbachips/Contact/contact.html - For those that want to take their tuning that little bit further. Well respected.
Forge Motorsport -

Road and Sport Developments -
