Boost gauge install

[Looker44]

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 where it’s plumbed in at

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

Look at this pic. Looks like he did it closer to the end on the line nearer the right angle, on the other side of that circle piece in the middle of the hose

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 [emoji1787]

The downside of the MapTap is the cost but I still think it is the best way.

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.

It’s the right line just the wrong side of the check valve it works perfect now
