Metro: thanks for the link. That thread got a whole lot longer since I last read through it. And I'll spend some time on it tonight
I have just a vacuum gauge that swings from 0 to 30 so the slightest bit of foot movement reflects quite clearly on the gauge face. Yes, you can lift off every so slightly and see a change on the vacuum gauge with no change on the speedo. If using a boost/vac gauge there might not be enough vac. swing to see the subtle changes.
