In reality, a carburetor perfectly tuned to its current conditions will make more power and be more responsive than a properly tuned EFI setup. The problem is, going back to one point I made, carburetors tuned to that level of perfection are only good for those conditions. Change the air temp enough, altitude, humidity level, etc, and it's all out the window.
EFI offers the adaptability to maintain almost the same level of power as a perfectly tuned carburetor all of the time. That adaptability also allows it to adjust the AFRs to be within it's designated parameters all of the time. This is the real advantage of EFI. Your fuel economy, as a whole in the real world where everything changes, will generally be better and you will consistently have nearly the best power possible regardless of what day it is, if you climbed a mountain, or the temp dips 40 degrees at night.
This is also assuming, like the carburetor, the EFI tune is done correctly. The other advantage of EFI comes in various options, like fuel cut at zero throttle, the ability to do lean AFR's at light throttle/cruise/idle conditions (very good tuning required here) but to really take advantage of things like this, full ignition control is also very important.
Take those factors into account and this is where the fuel economy of EFI really comes into play.
I would personally love to do a microsquirt system on my Hawk...and my Goldwing. I can justify it for my Goldwing to an extent, because a 20mpg gain (already documented on one GL1000) on that bike would save a ton of fuel and cash. The cheapest that could be pulled off would still be in about the same range as the Ecotrons system, if not a tad bit more expensive.
To keep with the cheap theme of the Hawk, myself and a couple of others have been eyeballing this system, and one member has attempted to use it on his Vader 125 with mixed results.

The 28mm throttle body offered in the kit will bolt straight up in place of the carburetor, and has a more reasonable entry cost below $300.
