As said, EFI won't make more hp. Hp is a function of proper timing and proper fuel ratio.
But those who make fun of EFI users don't understand the technology or advantages of computer controlled electronics.
Timing advance is limited to the curve of the weights in the distributor. EFI allows for infinitely adjustable timing curves to dial in efficiency and power at any throttle setting, any RPM.
Likewise on fuel delivery. Regardless of RPM or throttle, you can tweak your fuel delivery, to include completely shutting off the injectors at high vacuum, high RPM, 0% throttle. In other words, closed throttle coasting in gear; which can help increase fuel economy ever so slightly.
Carbs are cheap, easy to use, and effective, but EFI is superior in tuneability and efficiency.
All valid points. But after a half century of use, most guys today cannot/will not tune much more than the main circuit on their carbs. The real appeal of EFI for most guys is that IT'S SUPPOSED TO TUNE IT'S SELF. The reality is that sometimes it does and sometimes it doesn't.
But let's be honest, getting the real advantages of port EFI with optimum timing curves is really beyond most guy's abilities. And probably beyond their desire to even try. Which explains the attraction of plug and play.
The EFI that most muscle car guys buy is not much more than an electric carb whose benefits could be enjoyed with a carb that is properly tuned by a good carb tuner. And for a fraction of the money.
Besides, the EFI system you buy today will be obsolete in a year and you may not be able to get key service parts in a few years.
So while computer controlled fuel and ignition systems have the potential to be infinitely superior, it can only reach that potential in the hands of an experienced, competent tuner. Which, in the real world, rarely happens. Sorta like a carburetor.
