Boost gauge isn't working?

hey guys, just fitted a boost gauge with the help of a friend but the needle is all the way below -30psi and goes up slightly when on boost, everything is tight and cable tied, all straight. Here's a video

Where did you mount the boost sensor?
(or is it mechanical??)

It's not mounted properly as of yet, I've had a look online and it's a dodgey gauge. It's on a vacuum line
