#7769, "RE: What is the stock engine vacuum supposed to be? 7psi, or 14psi of vacuum?" In response to In response to 0 Nov-11-05 02:24 PM by CarbonFiberRST
the profec reads psi. the boost gauge reads in/hg, its different. but it seems that 1psi is approx. 2 in/hg. Notice that the area on the boost gauge dedicated to 0-30psi is 180* and the area dedicated to 0-30 in/hg is about 90*.
