Is my boost gauge not calibrated?
This is a new boost gauge that I just installed. I thought the needle has to be sitting inside the center of the box when it's not in operation. Please correct me if I'm wrong.

the reason it isnt right at zero is sometimes different atmospheric pressure than where the gauge was calibrated or just needs to be adjusted.
im pretty sure that gauge can be calibrated to read right, no idea how tho

no it wont, pic is of a vac/boost gauge, it should be at 0psi/0inHg when the car is off, just like it is

Now I know why my car ran out of gas at a 1/4 tank....

The only boost gauges that are truly accurate are electronic sensors which are then compensated with a separate barometric pressure sensor. This is something you will mostly find in OEM systems. I've dealt with my share of Autometer gauges. They vary a little bit but they aren't going to rest right in that 0 range usually.

Any cheap spring type gauge is going to have some degree of error, it appears yours is just more pronounced than most. I use a spring type, but mine goes back damn close to 0 when it should. Your gauge is not electronic and so it SHOULD rest at 0 when the motor is not turning. arghx is right. It's not super critical for most street purposes; it would certainly bother me, but I'd just get a different one instead of spend 3-4 times as much setting up an exacting gauge system.

dude, it's a monitoring device. it's like you saying "i know my fuel tank is full so i don't need a fuel gauge" or "i just added coolant so i don't need a temp gauge"

dude, im saying if its a half a pound off its not a big deal
your coolant and fuel analogies are stupid because those are things you can check at any time you are driving, boost is really important when? under full throttle and there is so much going on who is actually looking at the boost gauge? you have the tach and where you are going to concentrate on

That way if something decides to stick and I overboost, I notice it and don't lose a motor. Just personal opinion though. YMMV.

if you are staring at the boost gauge who is staring at the tach? lol
i think you can hear a overboost quite easily, still we are talking about MAYBE a 1/2lb
OP should verify boost with another gauge, that might just be where the thing sits
when I am in full boost its not always a dead straight road in the middle of the day without a single car on the horizon

its an Autometer
Anywhere in the "BOX" is Zero lmao
Even you questioning if it is off, justifies that perhaps you should change it. Just saying.
Im not hating autometer, if i had a domestic car I would rock them, its just that if it leaves you questioning it, then yeah it speaks for itself.
If your not even planing to run even over 1bar, id change that gauge out to one that doesn't read to 30psi so you can get a more accurate view.
There are alot of good quality gauges that dont cost alot, like used gauges.

you guys cant blanket statement autometer gauges, I dont know if you have seen their entire line they have way more then the cheap comp gauges
all of nascar- those guys must be wrong, nhra, all fools
but if its made in japan it has to be dead ***** accurate right? Autometer has stayed in business so long with inaccurate gauges because everyone else in the world is stupid and we are all so smart
