Chip Help
As of this writing no company has released a chip for the '00 1.8T, so no recommendations can be provided to '00 owners at this time. However, there is a wealth of chip information available in the AudiWorld archives, and on the web, for '99.5 and earlier 1.8T models. I'd strongly encourage anyone who's interested in this subject to search the archives and read at least some of what's there. Below area few URLs that may be helpful in answering your questions.
