they said that -.5 at idle is about right(0 in an ideal world). if its at -20 then there is somthing wrong with the compression in the engine or the connection to the boost gauge is in the wrong place. i still get a reading of 7 when at full boost witch is correct for a stock sr20det.

what unit of measure is your gauge in?

the numbers you are recieving here are for boost PSI and vor vacuum IN/HG (inches of mercury) sounds like your system is running on somthing else (BAR possibly)
