It will NOT increase HP over a PROPERLY sized, jetted and otherwise properly operating carb

EFI varies IMMENSELY as to amount of work, cost, and problems. I started with used systems to learn, and have been happy, but the cost can get to you.

For me, it works, others, not so much. Be prepared to do a LOT of study and research

Wiring is an issue, as delicate circuits can pick up RFI/ EMI from other circuits and cause problems. Bear in mind that the auto industry has spent BILLIONS learning how to design and implement EFI and keep it working properly

For me, the one big thing "plus" for EFI was vapor lock problems with modern fuel, and better startability duo to fixing fuel boil on shutoff
