Pro-Flo 4 puts an injector at every port with fuel rails on the manifold, which is what separates it from a throttle body EFI kit that still relies on the intake to distribute wet fuel. It ships with pre-loaded calibrations and self-learns, so no laptop tuning session is required to get the engine running, and the E-Tuner app handles adjustments over Bluetooth from a phone.
