Hey guys I’m brand new to turbo cars and after having my fiST I knew that I needed a boost gauge so I bought a gauge and the ATI vent pod and began wired it up with help from the posts on here (thanks guys) and then began plumbing my line I went through the fender to plumb it and I had a buddy help who told me where to t my vacuum line in and all I have right now is a vacuum gauge it won’t read boost it gets to 0 and won’t go further I will attach a picture of where we teed the line in at any help would be great thanks!!

There is probably a check valve in that line and you might be on the wrong side of it. I have not added one to mine so I wouldn't know specifics, but have installed them before on other cars

That’s kinda what I was thinking after doing some research but I wasn’t 100%

Yes that’s kinda what it looks like to me too now to figure out a way to move it to see if that does anything at all

That’s exactly what it looks like and that’s where I wanted to put it to but that’ll be the last time I listen to him lol

The best place to connect a boost gauge on the FiST is under the MAP sensor using a MapTap or similar.
This way none of the plastic hoses need to be cut and you can always return to 100% OEM easily.

I knew of those but I figured since my buddy had installed boost gauges he knew what he was talking about

Right that was a big downfall for my atm but I’m hoping if I move it to the other side of the valve it’ll work fully

If that's the line I think it is, the line you've tapped into is before the throttle body and thus will not read vacuum, only boost. You need a MAPTap or similar device to get boost and vac.

EDIT: wait, you're only getting vacuum, not boost? Maybe that's not the line I think it is. Hm.
