One hting to keep in mind regarding the Dali website is that Mark Johnson has (obviously) no love lost for Mark basch. So take that under consideration when you look at the website info under Dali.
I'm personally very happy with my bbsc. Mark Basch has gone out of his way, multiple times to answer my questions, tune my car, troubleshoot issues, and warranty a couple items. The car idles and drives as stock, other than at WOT. No stall issues, no cold start issues, and dependable performance to boot. I think there are in the neighborhood of 170+/- BBSC's floating around out there, FWIW. You only hear from a small percentage of the owners on prime, for better or worse.
If you don't tune the car, expect trouble, and don't whine when it happens.
