Gary--

You have the Air Flow Meter pinned WFO, when it's on gasoline?
Hmmmmm-----

Interesting.

So therefore, you are by-passing the computer when it is on gas.

The computer thinks that the AFM is wide open all the time?

More interesting------

I have a hard time understanding how in the hell, the thing would even
run at low speeds without blubbering, due to an over rich signal coming
from the AFM, to the computer.

I just can't see it functioning like that.

And you can't realize any different fuel economy whether it's on propane
or gas?

Propane delivers less MPG than dino fuel, so I would think that there
would be a significant difference.

And let me reiterate, the shortest distance between two points is a
straight   unobstructed line, and you start adding flappers, elbows, and
butterflies, the path become choked, regardless how you look at it.

So in theory, I ain't buying it.

I believe that there is a way to cause the Vanagn to get more air, but I
think it would be labor intensive, and monetarily cost prohibitive, for
the small increase in overall performance gained.
