Agreed, I recently just changed my driving style and have consistently been seeing 23 MPG in my 99 XJ, when I previously averaged 20.5 MPG.

I would like to see more of a technical write up on this "EFIE" device though, to see how it actually claims to work. I am still banking on Scam, but like with anything, I am open minded and curious.
