Alright I got mad about the thing acting poorly as described in the attached text file (the original post before I edited it & wrote all this).
So, being pissed off, I did what I do best when mad. I had a crazy idea and ran with it. Lol, see the pic in post #2. Yes, yes it is a dirty sock I found in the garage.
So, with the sock-filter I took it around the block real quick. It no longer dies at ~2500RPM. It has a real crappy powerband all around, but it does not die. So, what does this mean?
It means the obviosu that I have sorta known all along about a MAF sensor. The thing is calibrated not only to the housing it sits in, but to the intake hoses & stuff sitting before it. When I bench-tested it, it was not on the OE airbox. Now, since there is a real short space between the airbox anf the MAF, and there is a square-to-round transition, I bet it just won't work right with the thing. I AM going to re-calibrate the MAF in hopes that this thing will actually work right in the airbox, but I have my doubts. Corss your fingers & pray to the fluid-mechanics gods.
So, whether or not it works with the OE airbox is one issue. The other is...some people who would want one do not use a factory airbox anymore. Since this MAF is seemingly really cranky about this stuff, it would behave differently (potentially) with a cone filter.
So, this brings me to the bad news. Say I get it working 100%. It might not be as cheap as I had hoped to produce. I might have to get custom ABS fittings made that are required to be used with this to ensure that every install works the same. I hope it does not come to this as I know everyone wants to have a cheap MAF converter available. I think I am about done messing with this for the weekend though...I have to get ready for my Half Dome hike...we are heading to Yosemite around midnight and starting the hike at ~3AM...you can carry a lot less water when hiking at night.
