Carbs can do anything a injection system can do. Except make quick changes to the weather and elevation.
In fact I bet a carb tuner guy can show significantly better mileage with a carb. This is because most injection systems--from the factory---keep the A/F ratio at 14.4 while acarb guy can tune to 15.5 if he is good at it.



We're not talking factory efi here, and with an aftermarket efi, you can tune the a/f to wherever you want it. With a megasquirt system for example, you can set the desired a/f ratios for all vacuum/rpm combinations and the computer will recalibrate itself on the fly to achieve those results. Definitely much harder to do on a carb, with the big plus of the efi system being it automatically compensates for differences in ambient temp with closed loop wideband o2 feedback. But for your average weekend warrior that sees a few thousand miles per year, do you really benefit that much by that level of control? Only you can answer that one...
