There are some great videos on Youtube related EFI v. Carbs and tuning. I'm kind of a Youtube junkie.
Here are a couple videos that compare EFI and Carbs.
This one shows a challenge between one guy tuning a carb and the other using EFI. My take away was that it might be worth consulting a pro when you start out with either one. https://www.youtube.com/watch?v=ZGlRiapBEeY
