I made a flow tool from a hardware store 1/4 turn valve and pipe fittings, some leftover -6 AN fittings and line, and a decent gauge off ebay for about $30. I put a cap on the end of the outlet line and drilled a .073" hole in it. I chamfered the hole so it'd be a little nicer flowing.
I borrowed my buddy's really nice and expensive flow tool he bought from Gene Fulton to compare. They read exactly the same. I tried them multiple times and even swapped the orifice fittings, same result.

Chip, you should just ship that to me since you're done with it and have yours figured out!
