Message	Well I got an aftermarket boost guage in my car finally. Bought the Z series since its a close resemblence to the stock guage faces. Anyways just a couple of questions. First off does the vacumn pressure look right? It is reading more vacumn then what the sock one says, of course that could be because the stock one is probably inaccurate. But is 15 a normal vacumn pressure for idle? The reason I ask is because the guage makes like a swooshing sound at idle, and then once you reach zero the sound stops, and then once you hit boost you can hear it again. Dont no if it is a leak or if that is normal to hear the sound through the vacumn line. My mods include almost full exhaust, intake, intercoolers, and a stage III ecu. I am hitting 9.5-10psi, and that is without the boost jets in. Is that the normal range? Anyways I am just making sure everything is right, so any input would be appreciated. Thanks. I like the way it matches the stock guage faces.
