How much vacuum does the ECM require on an LG4?

Just wanted to see if anyone knew how much vacuum I need to keep the ECM happy. Is this a pretty standard setting over most of the emissions systems? I ask because mine is the oddball "C4" (as in emission system name, not Corvette type) emissions system used in California.

Thanks,
Matt
