boost gauge reading

[Lee.S]

I bought the following boost gauge of ebay

I temporary connected it up to dv and on idle its reading around -.7 is this normal when I rev it jumps to around 0. Not 100% sure where to feed vac line though I have found the grommet under pollen filter area feed it through and its come to where side panel is but do people route it under dash or along top of dash?

thanks.

Bought it off some Norwegian site but the name is "Prosport Premium Peak - Boost" if yerr interested, think there pretty much used, can set overboost warning and see boost peaks after a pull without having to watch the gauge while driving.
