The only part that I was able to see during my short time underdash, was a metal diaphram, with a nipple in the center -- the diaphram was about 1.5" in diameter, and there were two wires going into the back side. When the vacuum line is disconnected/plugged, the boost overshoots to 20, then backs down to 10, then drops to base boost. When the vacuum is reconnected, the boost never exceeds 15 PSI, drops to 10 and then rests at base boost (6). The boost surge to 20 does add some power, then it falls flat -- probably too lean. This is all at WOT in third. Everything is stock on the 93 Commemorative.

Once I find the best stock power setting -- it really runs good now -- then we will be looking to make some small changes to improve the low end. Not looking to go into hyperdrive -- subsonic is fine for now. Also, we are experimenting with a MBC+A unit.
