Hmmm...mine says 0.0 psi. I'm nearly at sea level. Here's a WAG: Could your 0.3 be the result of an atmospheric correction for you? I think absolute pressure is 14.7 psi at sea level, so a few hundred feet - or thousand feet could cause the correction to be easily off by a few tenths. Unless you had a 0.0 psi earlier and did a modification to the vacuum system, I wouldn't necesarily jump to a vacuum leak being the cause of the 0.3 psi reading while idling.
