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 replaces your carburetor and intake manifold with a complete EFI setup designed to improve throttle response, fuel efficiency, and overall engine performance. It's built for a range of vehicles, including popular models like the Chevrolet Camaro, Corvette, and Pontiac GTO, offering a significant step up from older fuel delivery methods.

At the heart of this system is a new, compact ECU with an upgraded, faster processor and a waterproof design. It communicates wirelessly via Bluetooth to the Edelbrock E-Tuner 4 app, available for Android and iOS devices. This app simplifies tuning with a setup wizard and allows for advanced adjustments to air-fuel ratios, ignition timing, idle speed, and more. The system comes with a satin finish Victor Jr. rectangle port intake manifold and 35 Lb/Hr injectors, capable of supporting up to 550 horsepower with 58 psi of fuel pressure. Edelbrock includes 80 dyno-developed base calibrations to get you started, and the ECU's self-learning capability continually refines the tune for optimal performance.

This Pro-Flo 4 system offers a powerful and user-friendly way to modernize your LS engine's fuel delivery. It eliminates the need for laptop tuning, allowing you to monitor engine vitals and make adjustments directly from your smartphone or tablet. For those who want a complete package, Edelbrock also offers kits that include a 7-inch Android tablet with the E-Tuner 4 app pre-installed.
