Boy, that's a generalization sorely in need of a good kick...
Just because some MAF cars have not benefitted from a WAI due to compensation by their engine computers, that does not mean that every single MAF car out there cannot benefit. Wouldn't it be surprising to find out that this model of Ford Focus actually did benefit from a WAI? In terms of improving fuel economy, at least the WAI has a good sound basis in theory, whereas ram air does not even have that.
Then again, with regard to the OP's improvement, I guess we'll never know how that happened, now, will we?
And again I must point out that I did not say that the OP did not actually see any gains. I said, and I will continue to say, that the OP has no clue how the gains were made.
