"Additionally, I'd like to also offer the OE CSL Camshafts for those that want to keep things factory BMW and for cool factor, as well as OE CSL Exhaust Valves, and OE BMW (Non-Coated) Followers. For those with CSL airboxes, the CSL Cams should keep things simpler as you could run the base CSL tune file without worrying about adjusting for cam values. Please note that these cams do not count toward the 21+ orders needed for the Cat-Cams Group-Buy. There is no minimum order for these OE BMW CSL parts.

*for reference, the stock M3 camshafts are 260/260." |
Does that guy work for Cat Cams? Because Cat Cams clearly specify 269/270 for the stock cams on their website, they don't even have cam specs for the CSL. That "Dr M3an M3" guy is using the same source of information for the OEM specs as you linked to.
