There were quite a few that ran that deal. As I understand it, there became a big problem with getting the supercharger serviced. No other blower manufacturer would touch them. And Gibson/Miller were to busy to do them at the time. My guess is that either the lesser amount of people running them created less demand for service, and they had time to service them, or someone else started doing servicing. Yeah, the PSI was such a huge step up about two years ago, that many teams dropped their old set-up and went with it. Made the other supercharger manufacturers try and play catch up.
