boost gauge install problem

[fordfarmer11]

hey y'all, trying to get my boost gauge installed and in my infinite wisdom tee'd the first line i saw, which happened to be the red one going to the wastegate. now my boost gauge goes up to about 5 at wot and spikes to 10 as i let off. I am assuming that i need to move it to the green line? or would i be better off tapping the manifold? Or could it be easier than that and just replave the line that i kinked pulling thru the firewall? I{ think i got the kink out, but its a small hose so could that be the issue?

COuple other things, for my EOT and ECT sensors, I ordered the tee from glowshift to put them into the stock sensor area, but am i going to need an adapter from the tee going into the stock sensor?!

Sorry For all the questions! Thanks in advance!!

OK so did you move the T fitting to the map sensor tube? It goes from the cold side of the intake horn to the sensor off to the left and is in a flex loom tube. Let me know if you need a pic. Don't tighten the little brass fittings too tight or they will kink inside themselves and kill the flow readings. Alternatively if you can remove your Air Intake Heater and replace with a plug that has a boost tube fitting you can install there.

the green tube i assume your talking about? No i have not yet. I wanted to get a few answers first. Will the green one read closer?

Both of the lines on the right side of the motor are vacuum lines. The one you need is the line that goes from the spider pipe left to a sensor mounted on top of the heater box. It's a rubber 1/4" hose similar to a fuel line. Put a tee in that or drill and tap a hole and adapt the boost line to the spider pipe itself.

by spider pipe do you mean the pipe going from the air filter to the turbo?

[jesilvas]

Spider is the pipe with five ends on it. One to turbo, two to heads, two to IC pipes.

ah okay, so tap into the aluminum or whatever that is then. how do you keep the shavings and stuff from going into the motor then? OR what do i have to do to delete the AIH? Sorry I am a 6.0 guy, dont know much about the technical stuff of the 7.3's

[jesilvas]

You pull the spider off. Or you can use an AIH delete w/tapped fitting for boost gauge from RiffRaff. Or you can tee into the rubber line coming off the spider going towards the pass side to the MAP sensor.

[fordfarmer11]

they all are fairly close in accuracy no matter where?

[desertdeer]

find your map sensor and tee the line that runs from it to the intake spider. its way easier and will save a ton of time.
