1999 Chevrolet Express 2500 Fuel Injectors

The Edelbrock Pro-Flo 4 EFI Kit No. 35780 for Small-Block Chevy engines with Vortec/E-Tec cylinder heads is a fully sequential multi-port injection system designed with a fuel injector strategically positioned in each runner of the intake manifold to deliver the best fuel atomization and most even distribution to each cylinder. This system features the high-performance Victor-style single-plane intake manifold that comes preassembled with high-flow injectors, fuel rails and 4150-flange throttle body. All supporting sensors are included along with wire harnesses and ECU. The Victor manifold is designed with a larger cross-sectional area in the plenum and larger runners for high-horsepower and/or large cubic-inch applications. The manifold is also 0.75 inch taller than the standard LS3 version to promote smoother airflow into the rectangular-port heads. This kit uses 29 lb/hr injectors and is rated for 450 horsepower at 58 PSI of fuel pressure. Calibration of the Pro-Flo 4 is a simple process with a Setup Wizard providing guidance through the E-Tuner application’s initial programming. Once provided with basic information such as type of engine, cubic inches, firing order, and cam profile, the E-Tuner App then selects the most appropriate base calibration. Once the base calibration is set, the self-learning E-Tuner App takes over to continually maximize the fuel map for your specific engine configuration, even compensating for changes in altitude and weather. The E-Tuner App provides more advanced tuning options that allow precise control over cold starts and acceleration while retaining the simplicity that Pro-Flo systems are known for. The exclusive Edelbrock E-Tuner 4 app is Free and Available for Android and IOS based smart phone or tablet.
