F.I. Tech or Holley sniper. Opinions from users.

I respect your opinion, Andy and I am glad that you didn't take my words as a doomsayer crying that the sky is falling.
I agree that these systems require a deeper understanding of the program. That is one of the reasons that I am skeptical. I also agree that like many other forms of new tech, it should improve with more development.
With a carb, you can be a simpleton and still keep your car running.
With EFI, at least as it is currently, you either gamble that it will work or you educate yourself on how it works and how to fix it if/when it fails.
I am stubborn to accept new things unless they are a huge improvement over an established standard. I don't have a car that is driven from sea level to 14,000 feet in a day. I don't live in a cold climate. I don't drive my classic every day. The features that EFI offers are not enough to sway me their way....yet.
