Most accurate tests by the most skilled mechanics show not much difference between carb & EFI on either power and mileage. However, carbs go out of tune much more often. Therefore, most folks with carbs are driving them around in an out-of-tune state. That's why EFI is much better overall. With a computer controlling the tune (and able to change as parts wear) you really don't need to do anything except change plugs every 10 years or so...
