I don't know. For one, because fuel injection is already tuned. You can go leaner at the expense of more NOx, but other than that, you usually don't find some car with a fuel injection system that's all out of whack going way too rich and/or way too lean.

Also I don't believe there's a huge difference between fuel injection and carburetion in terms of fuel mileage or performance. You can be more accurate with fuel injection, but I don't see how you can get huge gains going from "already pretty close" to "almost dead on".
