Well first off im installing a boost gauge, now what im haveing problems with is my boost gauge is reading negative for some reason.
I really dont know much about gauges tbh, never had to deal with it before and any help would be great.
Its going into the negative everytime and im useing the proper connectors etc.
 


Have you taken it for a ride, or are you just looking at it while idling? The gauge will be in vacuum until you put load on the engine and create boost.
 
Your probably right guys, I might as well go try then because i was only doing it at idle. Going to go for a ride then, ill tell you guys what happens
 
Two things. First what should it be idleing at or what should it be at when not pulling boost.
Second can you guys post a picture of how you ran yours if you dont mind?.
 
Vacuum is measured in Hg/in, boost is measured in PSI (pounds per square inch). I suggest you do some internets searches and some reading to educate yourself what they indicated and how they are measured. Most modern internal combustion engines at idle will have around 17 - 22Hg/in, and the stock L67 will have around 6.5-7 psi boost.
