Is there a way to take a boost gauge apart and make the needle go back to 0? When my car is off the guage reads 2psi. Which I would imagine would make my readings off the whole time! help!

 

if u pull the light out its slot u might be able to get ur pinky in there and adjust the pressure ring by applying physical pressure to it. when u touch the ring your boost gauge will go up, if u push it too hard it will actually stay a little higher than what it thinks is atmospheric pressure. probably not the best way to do it but it should work

 

Unfortunately I need the needle to go down.

 

sorry i read it wrong....i have no idea how to fix that, sorry

 

I'm guessing its an autometer gauge. If it isn't then sorry. If it is, its pretty common and I would upgrade to a better gauge with a sending unit like a greddy gauge.

Even if you could fix the gauge, would you trust it?
