Try looking at the "best you can do for your car" thread here on this board, as well as OughtSix's thread about the same.

I've collected all the parts other than a little hose required to convert my 500SEC to EFI (going with MegaSquirt), and will be documenting all that I've done when I get started on the actual conversion.

As far as mileage goes, I'm not sure how I did it, but the last tank through my SEC was highway mileage, and averaged 19.3 over 360 miles. Odometer was verified over 20 miles against the mile markers, just due to thinking it was running a little off, but proved to be accurate.
None the less, I'm hoping for improvement with EFI installed and tuned.
