Check the archives. There have been at least two group purchases of the
Aussie Performance Chip as far as I know. The last was organized by Tom
Forhan.
Note - it does very little without ratio rockers and other "free breathing"
modifications to the engine.
Also do a search on posts from Robert Lilley circa 1999, and search for
occurances of "Half Lilley" and "Half-Lilley" within th last 18 months. You
will find a LOT of information
