From what I've read, I tend to agree with DaytonaTurbo. Also the ability to lean out a map for a cruise situation to maximize fuel economy is like changing jets in the carb based on driving conditions. You can only get so close, but have a much broader range of adjustment with EFI and the same injector. Anyway, SMPFI > MPFI > TBI > Carb... as I read it... Anyone else?
