That's the exact setup I run.
On the flow valve, use a clear piece of tubing to the stinger for testing so you can see when it opens/flows and adjust as necessary to get it where you want it in the rpm range.
Thanks!
Any hint as to what RPM the flow should come in at (2k - 3k rpm)? I think you want to keep the box dry to a point off idle/low rpm... just not clear where to start bringing it in, since extended light throttle might lead to coupler melting? Or not really concern with headpipe injection?
