What is a normal idle vacuum for a cammed 5.3L? My cam is 212/212 .561/.561 114 LSA, that's an overlap of -16 deg. It idles warm at 15-16 inHg at ~630 rpm, three different gauges say the same thing. I thought it was supposed to be a little higher. It has not been tuned for this cam yet.

I'm trying to figure out if I have a vacuum leak. Thanks!
