The Easy Street EFI System Kit is a FiTech Fuel Injection System rounding out the Street Series line. The Street Series includes the 150??400 HP Go Street, the 200??800 HP Meanstreet, and now the 250??600 HP Easy Street specifically designed for naturally-aspirated engines. With a classic gold finish, the Go Street Series EFI System may have the looks of a factory carburetor, but the similarities end there. The pre-programmed assembly bolts right into place on the squarebore intake manifold and requires only a minimum of inputs to fire up. The Easy Street accepts the tach signal from the coil negative, an HEI distributor, or from a CD ignition box for a simple installation. A fast-reacting wideband O2 sensor is supplied in order to monitor the fuel burn, which signals the self-learning technology of the ECU about adjustments to the mixture. This results in smooth performance anywhere from idle to high rpm's.
