Hi=20 Ed,
 
Do=20 you think there's a chance this regulator only adds pressure when = it sees=20 boost, and can't reduce pressure for anything less = atmospheric?   As=20 we've discussed, the feature really is meant for=20 turbo/supercharged usage, so perhaps they designed this regulator = specifically for that purpose, and allow it to stay at a fixed=20 pressure when not under boost.  Just a guess, but it = would=20 explain how you've had two of them, and neither worked the way we = would=20 expect.
