I looked on pmgfi.com and Its not helpful and none of the post i could find searching help me either.
I'm using a plx m500 and i need to know what vaccum and psi would be at each voltage.

0 volt =
.5 volt =
1 volt =
1.5 volt =
2 volt =
2.5 volt =
3 volt =
3.5 volt =
4 volt =
4.5 volt =
5 volt =

I know someone has to know what it should equal. My friend has a innovative and im using plx and i know the voltage is off on both our cars becasue mine says im showing boost on an all motor car and his is saying he is hardly ever showing boost..when his boost gauge says he is. So if anyone knows the real equation let me know.

Thanks in advance
