That's pretty much in line with what I have found.

I would be happy with 20/30% improvements.

15 to 30% over a drive cycle (tank-to-tank with the driver unknowing of the devices presence and operation).

I've measured 50% on old carburetor engines, but that is to be expected. And that was at one singular point on the fuel/load map.

The modern gasoline engine is already quite economical. The incremental gains in fuel efficiency are pretty much what one would expect as engine controls improve.
