A couple comments: First, the governor is a great thing to do. I'm guessing a lot of readers would appreciate some closeup photos where this is, and how to disable it. Also, (not sure) but I think your pulse tubing routing is a little unique in that it sounds like there are TWO sources, and the exact routing and theory behind it might have been bypassed. I didn't read all 4 pages of this forum, so I could be mistaken. If not, how about a pneumatic chart of this, and the theory behind it, as opposed to simply intake. Thanks!
