Mike, I did that just a couple of weeks ago after I installed the HeliBoard. The plenum is on the wayy, I don’t have it yet but will in a week or two. Hopefully it allows me to get the power back to 980 to 990 with the RD Monsters and restore some efficiency. The bottle reg is a Huma. Set point is 190 bar. I’m trying to get the gun to shoot all shots exactly the same and eliminate those few flyers that “could” be caused by a variance in harmonics.
FYI, Bobby Corcorran @arzrover did the initial tune on my gun and did a great job
