Actually it wasn't. If you're so sure I'm wrong they why did you start this thread? You obviously have your mind set on getting better mileage.

No they don't always put in the same amount of fuel at a certain RPM. It depends on vacuum (how much AIR is being put through the motor). For example, you could bog (kind of hard on an automatic) at 2k or you could be at WOT which = 0 vacuum. Do you think the same amount of fuel is being dumped in when your bogging as when your flooring it? If you don't understand, look at this. This is the program I used to tune my integra. The Y-axis is RPM. The upper X-axis is vacuum and the lower x-axis is boost. This is an unfinished map but it's just go give you an idea. Pick any RMP you want. Follow it over to the right, the further right you go, the less vacuum there is which means you're stepping on the gas more. For the n0Obs, the higher the number inside the chart means more fuel (more red). and they call it air/fuel ratio for a reason, not rpm/fuel ratio.
And when you talk about making "more power at lower RPMs". What is power? It's an explosion. For something to combust you need oxygen, fuel, and heat. To get more power (ie. bigger, stronger explosion) you need more air and fuel. You can't increase just one and expect the same results. The computer puts in the proper amount of fuel based off of a MAP like the above diagram, or some cars use a Mass Air Flow Sensor.

Yes I have one of "dem" intake spinners, it's called a turbo.
and the butt dyno can be very deceiving when it comes to a new performance part and how much power you gained - think placebo.
