Boost gauge reading help

[bazrazmataz]

I've just fitted a boost gauge to my LCR and never had a gauge in a car before so am unsure of the readings. On idle it goes bellow zero right to the bottom of the gauge then once in gear I move up above 0 psi mine is stock seems to Max out around 20 but often peaks then drops back a touch so appears to not hold at max.

Are these normal readings what should I expect to see

Thanks

Lcr should be around -20 when at idle, then when accelerating and on the move anywhere between -20 and 14/16 for a standard lcr , its normal for it to spike then lower with soak. I'd say at 20 it might have been mapped though ? Should also when under De acceleration be about -5 more then idle so around -25

Hope that helps !

My vaccum gaube sits at around 25 hg when idle and when boost goes past zero ?

Should be postive of 0 on boost -25 isn't anything to worry about if it was -10 etc that might indicate a leak in the system
