On my autometer boost gauge(Yes i said autometer and before you guys start yelling at me for getting autometer i got it for cheap from a friend)...anyways back to my question. On the gauge when the car is off the gauge reads below 0 and when i was boosting 7psi it read 5psi. Is there any way to 0 the boost gauge?

Thanks

 

i thinik you should buy a new gauge.

i really don't think the time and effort is worth it to recalibrate it...upgrade to some GReddy gauges

 

You might be able to send it back in to autometer to get recalibrated. Don't give up until you try to contact the manufacturer.
