What they said.
Don't think you have to worry overly much about "killing" your fuel mileage going to and EFI as long as the tune is reasonably close. I went with a mass flo system and, once dialed it, got a slight increase in fuel mileage with no detriment to driveability with a slight increase in both HP and torque. The dyno curves however were significantly smoother after the change.
Probably the single biggest change is the consistency in starting. Doesn't matter if it's cold or hot, just hit the starter and it goes. Over the course of a season I end up running everywhere from sea level to 10,000 feet or more and the EFI does a great job of adjusting to the changes. With the carb it took some serious attention at the higher altitudes.
