I see this all the time when reading reviews of cars. For example, a while ago I was reading two reviews next to each other in the paper, the Jaguar XJR with a 5.0 litre V8 SC engine and the Porsche 918 with a 4.6 litre N/A. Yes I know there is quite a price difference there, but the supercharged Jag is 92.8 hp/litre and the N/A Porsche is 132 hp/litre.

Every engine produced today should be getting at least 80 hp/litre N/A before going FI.
Two problems here:

- Discounting overall powerband with max hp/litre metric
- Assuming that is indeed what manufacturers do. Many put FI onto vehicles because it's an easier way to meet gas mileage and emissions targets
