    Question boost gauge information needed please

    If you have a boost gauge on your sho/fzr/fzs how much vacuum are you seeing at idle and what type of gauge it is? Also where is your gauge hooked up at? Please post your information. My gauge is a Dyno tune digital and I show -8.3 to -8.8 at idle. My gauge port location is on the R&D mulit- port adapter at the map sensor.Thanks Tommy Jordan

    I get the same on mine Tommy...also using the R&D adaptor. One thing I noticed on mine is the sensor is a couple tenths off & doesn't zero out when I shut off the ski...shows .2-.3. It's the second one I bought from him after my original, which I bought before he was offering them sealed, got wet inside. The sensor that came with my first gauge always showed .0-.1 after I shut the motor off.

    Analog gauge coming off the R&D multi-port at the map sensor = -17.0 at idle
