Boxster (987) and Cayman bands are from the same troubleshooting page. Range 1 is 7,200–7,500 rpm there, while the 911 starts at 7,300. The v5 manual lists 7,300–7,500 for the 997, Boxster (987), and Cayman and does not make that split. This reading follows the troubleshooting page. Durametric does not publish separate base and S tables.
