Parish, that is why I asked about your 3rd pull, I noticed your HP/ TQ fell off with each successive run suggesting other factors may have contributed to the power loss and if true then its quite possible there is no power difference between open and closed.

I have a 2015 2SS/RS 6M. Most of the time i run closed (though I must admit open is growing on me, it's just very loud at start up, and until engine warms up). I clamp the actuators. and can easily reach down and slide the clamps off without looking under the car, putting clamps back on takes less than a minute. Of course I realize there are more elegant solutions for gen 5 owner like 3-way switches to control the valves from the seat (not the street..LOL), and you can always alter the wiring much cheaper then a 3-way switch as suggested by a poster in this thread. There is also the very convenient Palmer Engineering's Dashlogic than can close the flaps using the cruise control buttona, but I worry about battery drain with that setup as dashlogic connect to the ODBC II and I believe that connector is alway hot (though I'm sure stand by power is minimal, and my concern unwarranted, just don't like the thought of any battery drain, especially since I historically run closed most of the time, though I becoming more intrigue with stock operation lately which is open 75 percent of the time)

On your point about your flaps possibly being opened at WOT in stealth node, not sure however I have read the 2016 owners manual and there is brief mention not to run in stealth if you're tracking the car so I wonder why chevy would be concerned if WOT overrode stealth flap setting, it would suggest to me that it may not.
