Jerry, I saw your original post on Rennlist (we Pelican'ers tend lurk on both forums). I think Paul's direction is good...take the damn thing out of the equation and see what happens. The first step in troubleshooting.

JFairman knows his stuff, and as to whether 17 inches of vacuum (or 23 inches) is where it opens, what was quoted is most likely a Porsche part specification...and/or experience talking. Yours might be opening a bit sooner than intended, causing your rpm's to hang up more than they should. Let's see what disconnecting it does for you. I stll have my vacuum limiter connected with no problems as you've experienced. But what you learn, so shall we all!
