Hello, As a Newbie to the forum I'm looking for some info. I've bought a 2006 A4 Avant S-Line Special Edition 2.0T FSI. The spec says it has 220bhp compared with the standard 200bhp. Reviews say that the engine as been "tweaked" to give the extra power. Does anyone know how it differs from the standard spec? Has it been changed mechanically (eg different turbo) or are we talking an ECU tweak here? Any things I should know or look out for with this model? Any links to useful sites, articles or reviews would be great. Thanks.
