Thanks for the info guys. It seems that the only reason you'd have to come off the BOV/OC is a BO gas switch. In SCR mode, switching out the cylinders with QCs wouldn't be a problem, but I'm guessing it's not really possible if you're in full OC mode and breathing off the BOV 2nd stage and trying to switch from 1 mix to another on the fly. I've never had a BOV and the OC multiple gas switch problem was not something I had thought of. So you just come off the BOV and use the next mix 2nd stage, OK.

But in the event of doing an SCR BO, and then using the QC to switch mixes, is the water that gets in the line harmful to the 2nd stage downstream?
