I still feel that the puming losses are significant. In many cases, a car with WAI will see an improvement--likely due to the reduced pumping losses due to less-dense air.

If you're going to use the maximum power, or near maximum, that your engine can generate, you're already throwing fuel economy out the window. (Or out the tailpipe.)

Then again, some cars don't seem to respond that well to a WAI. The only way to know is to test one yourself--or to find someone with a nearly-identical car who has tested it on theirs.
