3 Reasons to Consider a Self-Learning Fuel Injection System

Tuning is rewarding when you want to do it, but aggravating when you have to do it. Today’s self-learning fuel injection systems give us the best of both worlds. The injection units quickly learn what the engine wants to run at its best and offers additional tools for those who like to tinker.

How do I pick the right size fuel injection kit?

EFI Kits are rated by the maximum horsepower they support with gasoline. But what about the smallest engine a system can support? Choosing an EFI system that’s too big will result in poor idle and bad throttle response, same as a carburetor. Keep reading to learn what affects these ratings and how to pick the right kit for your motor.

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:
