To really get any of the potential gas mileage benefit of EFI, I think it takes an EFI-friendly cam with like a 114 lsa that pulls decent idle vacuum. Running a lumpy cam and then tuning the EFI to compensate for and perform well results in no better gas mileage than a carb. Thats what my own experience is anyway. If the EFI controls the timing you can gain a mile or two in MPG improvement there with some tuning.
