What's your point?
The aerocharger has been defunct for a LONG while now. Sure, there's a few used kits floating around, but 1) turbo rebuilds are costly, 2) there are very few, if not only a couple, sources for rebuilding, and 3) the turbo itself is limited.
As for the Xios kit, while it's priced competitively, it's not exactly the most conventional setup. Whether that is a good or bad thing from a mechanical standpoint is an entirely different issue. Fact of the matter is, I've not seen any publicized 'real world' info or data concerning the kit, other than Dudley's. I don't recall reading about anybody else purchasing and playing around with one. That in itself has not help Xios' business case. For as long as they've been around, Xios unfortunately has not gained any traction, and I doubt they ever will.
