My Procom is set at 6 as well. I think I read somewhere in my research that 6 matched the stock number for the 790s and 7 was for the 865s. The other settings were for the various incarnations of the 360 degree motors. My bike was cold blooded before the Procom so it's hard for me to tell/remember if the Procom is anymore cold natured. I have found that my bike idles best at around 1100-1150 rpms, having a Speedmaster I have the tachometer so it's easy to monitor.
