If your Focus really is using a MAF and not the MAP then you have the effectiveness probability backwards. Apparently, nobody here has shown that a WAI works with a MAF (Sentra_SE-R ran the best test I have seen on that). I tested a WAI with my Honda's MAP sensor and found a modest gain in an ABAB test (see my signature file for the link).

In general, these benefits are close to the margin of error produced by driver variability and conditions, so a rigorous ABA test is the best way to try and see if something like this is working. When I bought my Ultra Gauge a few months ago I was amazed at the variability of my driving, even though I had been essentially hypermiling for years with the same car.

I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
