Tuning and Tweaking

Before you embark on "tuning" your ur-quattro, it is a good idea to get it inspected by a specialist who can recognise the various forms of limp home mode that most cars now seem to be running in. It might well be that replacing a single switch or vacuum hose can give you a bigger performance jump than any of the following mods. If you are contemplating something drastic get advice about the state of your engine first.
