The MAF sensor seems not to work, judging from tests people have tried here. I run a WAI with my MAP sensor. I have tested fairly rigorously in an A-B-A format (see link in my signature for test results). I have seen temps as high as the 130s without knock. I saw a significant FE gain.

Joenavy85 does it again! I think he is completely correct on why a WAI works with a MAP sensor. The design I use gets warm air from above the exhaust manifold and catalytic converter. (Pictured in my avatar.)
Good luck!
