Default making hole and welding bung on ETS TMIC

I am going to a SD tune and need to have a bung welded on my TMIC.

How do they drill the hole without getting the aluminum in the IC? Would hate to leave a piece and it end up in my engine..

Has anyone done this?

At one point I was going to install water meth injection on my STI but decided to go flex fuel instead. I had already purchased a Snow Performance injection plate that sandwiches between the throttle body and manifold. It has two 1/8" NPT ports, maybe your IAT sensor would fit if you purchased the plate?

Damn looking at the part and think this would work. Thanks!

You'll need this IAT sensor:

But the IAT is 3/8 NPT. Can I just cut the male connector on the SD kit and put the AEM connector on and plug in?

I would want to do some comparative feedback first. Your charge air temps are going to be different from I/C end tank-to-intake runner. Whether that's 10 and inconsequential, or 50 is anybody's guess. Tuners know what works with end tank temps, but I don't believe anyone has gone in this direction. Without proper testing, you're taking on that risk.

So no one has ran IAT in the end tanks before for a speed density tune? i thought it was common if not running a FMIC.

My mechanic with 15 yrs exp. working in Subarus told he would weld it on the IC.

I thought the spacer would be a better place since its right on the throttle body. However, with the spacer it will be near impossible to get the coupler on bc the extra 3/4" protrusion. Plus need an extension for the MAP sensor.

No problems with reading temp and running well on Speed Density tune?

My bad. For some reason I was thinking TGVs with secondary injector ports. Sorry!
