Boost Gauge Install Help...

[ToMang07]

Ok, I want to make sure I'm clear on this...

I have the Glowshift Gauges with the "Drill/tap" style connector, (NOT the "T" fitting) and want to be sure of this info...

In this write up, it says to drill/tap here for the Boost sensor:

How the heck do you get the shavings out? Do I have to disconnect everything and take it all apart just to tap this?

I understand the Exhaust probe is drilled upside-down and then vaccumed out to be safe.... but how the heck is this supposed to work???

not sure about the 7.3 but on my 6.0 i took the whole intake off to be sure there were NO shavings .

I don't know about turbos, but I had a delicate situation with hydraulics that need to be tapped. I used grease (axle grease I think) on the tap and in the tap flutes, did a few turns, pulled out the tap, cleaned it, re greased it and repeated until I was done. I did the same thing with the bit to drill the hole, but it was a brand new cobalt bit (rigid brand from home depot) and used low gear at slow RPMs on the drill. I did this AFTER the fluid filter (so the filter would not have caught the shavings) its been 2 1/2 years and no seal problems. I normally don't do stuff like that, (normally I would undo everything remove the hydraulic cylinder,etc.) but I was on the spot in the middle of a job. don't know ho well it would work in your situation but its an idea. Good luck.

Pull the inter-cooler tube off then stuff a rag in there past where the hole is drilled. After you drill & tap hole vaccum the shavings out then pull the rag out. You'll probably have to pull the IAH element out of the intake also. I'd say screw all that & put a T in the MAP line, that's where I put mine.

Yeah... well... I dont have the sensor or other stuff for the "T" line... its a digital gauge.

Why not just delete the AIH and use a plug tapped for your sensor?

Yeah, what he said... That's what I did to my yellow truck... bought a plug to fit the hole (it's metric, 22mm I think, almost 1/2" NPT) and tapped the plug for the 1/8" NPT boost line fitting... worked great for me, and got rid of the AIH...

What sensor? All you need is the T with the 1/8" comp fitting, it's the same reading in the MAP line as you would get tapping the spider.

Does deleting the AIH throw ANY codes?

Do you have to remove the whole thing? Any write-ups how to do it?

It's simple, unhook the wires, tape them up, remove the AIH, install plug. A 1/2" NPT plug can be used, but the threads are slightly off, and you bugger up the threads to where the AIH might not work again... I chose to get a plug with the proper threads, and drill/tap it to the 1/8" NPT fitting... basicly becomes a large reducing bushing, from 1/8"NPT to 22mm.

Will have diffrent issues with my early '99 truck, no AIH to delete, only option will be a "tee" in the MAP line...
