Anyone with recent experience chime in?
MPE with exhaust valve controller in October with no problems, ran the valves closed the entire time. However, was there a few months prior and even with valves closed, blew sound twice. Air density, wind direction, I donít know what other factors, but big difference from day to day.

Make sure you have a plan, it sucks to cut your day short for sound
