Boost gauge. Dumb Question.
So where exactly do I hook the other end of the tube up to?
Obviously one end goes to the gauge but where does the other end hook too?
I assume just somewhere on the possitive side of the turbo but are there any prefered places?
Thx

there are several options:
1)delete the air intake heater and put it in an AIH delte plug you can make or buy from one of the vendors here
2)tap the tube into the intake manifold
3)cut the map line and use the t-splice to mount the gauge

Just T into the map sensor line... all you need to do is just get a couple inches of hose and clamp it where it connects to the Y pipe then install the T then hook up the map sensor line... that way if you sell the truck you can just take out your boost gauge...
this can help visualize everything...

I and Pete F250_ are thinking on doing a pre and post IC. This will help you locate where your leak is. They have cheap Parker valves and then you can use one gauge and a valve and get pre and post IC readings.
The map line can BARELY be seen in the pic. Look where the red and yellow vacuum lines cross each other. That is the MAP line hiding in back inside a wiring loom cover.
The numbers will be a bit different, but a lot different if there are leaks in the IC/Cold Boots.

I dunno, never had any problems. I can make 25#s pretty easy when I want to. I do check my boots often and tighten as needed so maybe that's part of it.

Can't edit the above post. Now that I think about it I see your point. Still, I don't have any problems and never have. My truck runs like a scalded ape and I don't have any low boost symptoms like high EGTs or lack of power so I will leave mine right where it is.

On the flip side of all this, it just goes to show you how unneccesary the AIH is (in the lower 48). the AIH is in the direct path of the colder charge air after the IC. Why heat up the air you've just cooled down. (I do realize that you folks in Canada/ Alaska need the AIH, other wise the air would be supercooled and bring cylinder temps down)
