Usually with a vacuum leak your idle will go up. My SRT-4 was around 18-20 inches of vacuum at idle. That is why I was worried with the UltraGauge showing 9.X inches of vacuum at idle.

Did notice that fat rubber line that goes from the passenger needswings intake to the valve cover was kinked. Going to fix that soon. First blower car in a sense. Do these cars have boost leaks?
