Boost gauge reading

[99bluegst]

Hello everyone!! I am just wondering if some one had this problem before!!
Ok I just got a boost gauge and is reading -10
now my question is, is this normal? And and it read about 9 pounds of boost
or how much pounds is on a stock 2g gst???

Thanks!!!

Should be closer to 12psi for boost and around 18 inHg for vacuum. Still on the stock 2g bov?

Yes I am still on the stock one! So what should I do to fix my problem or what can I do to have good vacum reading?

Do a boost leak test.

Like 2gGSXEclipse said do a boost leak test. You can find a write-up on it in the tech section.

I would suggest buying a 1g bov or a good aftermarket one. The plastic bov I took off mine was so weak I could even blow through it with my mouth
