Can I run a turbocharger, supercharger, or nitrous oxide with my fuel injection kit?

Power adders like nitrous, turbochargers, and superchargers are a natural fit with EFI. If you want to use power adders now or in the future, buy an EFI kit that is Power Adder Compatible from the start. A power adder compatible kit will work fine with or without boost or nitrous, and it might be impossible to make a non-compatible kit work with power adders. Unfortunately, not all power adder compatible kits are created equal. They usually have:
