You've thrown posted a few pretty insulting things when discussing this topic too (giant cookie?). Let's all try to avoid them in general, OK?

A jump from 32 to 42 is a 31% gain. How is that not a big change in performance terms? That there's diminishing returns to improved mpg in general is pretty much besides the point, isn't it?

That's the best kind. That's what really matters to most of us, I think. Sure, it's nice to talk about theory, and nice to talk about experiments, but nothing beats long-term proof that it really worked for someone. Even if there's a placebo effect (not saying that about WAI/HAI in particular), who cares as long as it produced results? Results are what matter!

Unfortunately, due to the large quantity of variables involved, it's tough to find irrefutable results for either side.

However, I will say this: We have one experiment that squarely shows a real improvement, and have seen links posted by NovaResource to mixed (at best) results where the people doing the tests admit that it is not definitive.

Ahh, but it is something we can measure!

NovaResource keeps posting about a "10mpg" improvement as if it's some crazy unattainable number, but it's only 31%. It's certainly worthwhile and certainly significant, but it's not some crazy pie-in-the-sky achievement. I suppose it would be for a Chevy Nova, though.

Those are the ones that I pay attention to. If you use the same pump 3 times in a row and get the same mileage, change one thing on the car and see either a jump or a decrease in mileage over the next couple of tanks THAT is data I can live with.

I took it as extreme sarcasm. I apologize for misreading it. No tone or inflection.

Member cannot tell the difference between ABA testing and butt dyno.

Is anybody arguing that WAI has been definitively proved? That's not even the question I really care about at the moment. "Should I bother giving it a shot?" is more my focus.
