Edelbrock Pro Flo 4 EFI System Seq Port LS Gen III/IV Victor Jr Cath Port 550 Max HP 35lb/hr

If you're looking to upgrade your Chevrolet LS Gen III or IV engine with modern electronic fuel injection, the Edelbrock Pro-Flo 4 system is a comprehensive solution. This kit centers around a Victor Jr. single-plane intake manifold with cathedral ports, designed to work with a wide range of LS-based vehicles. It includes 35 lb/hr injectors, capable of supporting up to 550 horsepower with 58 psi of fuel pressure, making it suitable for many performance applications.

What sets the Pro-Flo 4 apart is its updated ECU, which is smaller, waterproof, and features a faster processor and a more reliable Bluetooth connection. This allows for seamless communication with the free Edelbrock E-Tuner 4 app, available for Android and iOS devices. Through the app, you gain control over critical engine parameters like air-fuel ratios, ignition timing, idle speed, and fan control, all while the system's self-learning capability continually refines the calibration for optimal performance. The system doesn't require a laptop for tuning, simplifying the process for both initial setup and ongoing adjustments, and offers multiple dash display options to monitor engine vitals.

This EFI system is a well-built package designed for enthusiasts seeking improved engine management and performance. It comes with dyno-developed base calibrations preloaded into the ECU, and the E-Tuner 4 app guides you through setup with a wizard. For those who prefer a ready-to-go setup, Edelbrock also offers kits that include a 7-inch Android tablet with the E-Tuner 4 app already installed. This system is a solid option for a wide variety of Chevrolet and Pontiac vehicles, including models like the Camaro, Corvette, GTO, and Silverado, offering a significant upgrade over older fuel delivery methods.
