Not quite related, but interesting...

Just one example.

There's tons of information on this, just look...

My brother and I plan on building one of these contraptions, but in the plans it specifically stated that using it on a modern (Computer controlled) engine would not do any good. I guess the computer messes with the mixture and negates the gains. I have an old Baja that we'll use, if we get a good working setup.

Anyways, if we could find more ways to reduce consumption without hurting the environment or Economy, I'm for it, but still skeptical as people are just going to jump into the latest Tornado or "Performance Chip" (Resistor) without doing all the research to see if there is any benefit.
