Fuel Injection is only a few % more efficient over the average small carbs. Now if you are talking about the difference between fuell injectors and huge doubble pumpers then the difference is huge. here are what is really the benefits of fuel injection and the reason car companies when to it exclusively
* Exhaust Emissions
1 Significantly reduced "engine out" or "feedgas" emissions (the chemical products of engine combustion).
2 A reduction in the final tailpipe emissions (≈ 99.9%) resulting from the ability to accurately condition the "feedgas" to make the catalytic converter as effective as possible.
* General Engine Operation
Smoother function during quick throttle transitions.
Extreme weather operation.
Reduced maintenance interval.
A slight increase in fuel economy.
With the computer metering of Fuel Injection the Catalitic converter can do its job more efficiently reducing polutants. Minute adjustment to a carb while the car is moving is almost non-existent
