Multi vacuum lines

[Sam's GSX]

Quick question, can I have 3 tee's tapped off the fpr vacuum line?
I've had my mechanical boost gauge off of it for over a year now and had no problems, but now I have aem tru boost and a meth kit that both need vac sources, will it mess my afpr up? Or it won't make much of a difference? Also if it won't work, can I tee off of the emission lines by the throttle body?
Thanks

You can run a simple boost gauge on the same source as the afpr, but the true boost has a map sensor correct? If so, you'll want a dedicated source and not too long. IDK on the meth kit. I recommend reading the instructions.

Just picked up the instructions for the first time ever, but it just says manifold pressure, so I will tee the meth to the fpr, as for the tru boost, I've been using a straight source but its before the throttle body and it reads quite a bit different at cruise (I know it wont read vac, but if rather it read 0 till I actually get into boost) oh well

With tru boost, you can log boost pressure to link.

If you ever remove the manifold, that will be the time to tap for all your pressure sources.

That's actually what I was thinking, probably the best way, also I can log boost on dsmlink with tru boost?

Sorry it does not have a map sensor. It's a boost controller. I was looking to buy one a while back but decided not to since they're pricey. For some reason I thought it came with a map sensor.

Ok no problem. I'll just have it on the fpr source for now, and down the road I'll tap more sources, thanks

Ideally, you want the MAP to have it's own short line to the manifold. I would not use a source before the throttle body. Only use it on the manifold and to a lesser extent the throttle body.

Yeah, I ended up having all three on the fpr for now, everything seems to be working great though, in the future when I take the IM off, I'll tap sources

When it comes time, research where the best areas are. There were spots on the 1g manifold that gave issues for map sensors.

Oh ok thanks, I wouldn't have thought of that.
