Hi all. Ive got an 05 plate 2.0 A4 Avant TFSi and want some more grunt. Ive seen that remaps seem to be the way forward as far as performance per pound goes. I have heard mixed reviews about pretty much all the main players but am tempted by AMD in Essex or Jabbasport in Peterborough. Anybody got any tips? Also looking at the new Forge atmospheric dump valve that has just been released for this car and i supposed to make the turbo run cleaner (less run on). They are just under £60. Im asuming these make the "PPPSSSSHHHTTT" sound but i dont want anything too chavvy. Anybody got one of these on?
