Edelbrock Pro Flo 4 XT EFI System Seq Port LS Gen III/IV Cathedral Port 550 HP Max 35lb/hr Black

If you're looking to upgrade your Chevrolet LS Gen III or IV engine with modern electronic fuel injection, the Edelbrock Pro-Flo 4 XT system is a comprehensive solution. This kit replaces your older fuel delivery system with a sequential port EFI setup, complete with a Pro-Flo XT intake manifold designed for cathedral port heads. It's built to support engines making up to 550 horsepower, using 35 Lb/Hr injectors that operate at 58 p.s.i. fuel pressure.

What sets this system apart is its updated ECU, which is smaller, waterproof, and features a faster processor. The Bluetooth connection has also been improved for better reliability, making it easier to tune your engine wirelessly. You gain control over critical parameters like air-fuel ratios, ignition timing, idle speed, and cooling fan operation, all while keeping the user-friendly setup Edelbrock is known for. The system works with the free E-Tuner 4 app, available for Android and iOS devices, which uses dyno-developed calibrations and a self-learning capability to optimize your engine's performance. This app also provides multiple dash displays so you can monitor your engine's vital signs right from your smartphone or tablet, eliminating the need for a laptop for basic tuning.

This Pro-Flo 4 XT system fits a wide range of Chevrolet vehicles, including popular models like the Silverado 1500, Camaro, and Corvette. It comes with everything you need to get your LS engine running on EFI, offering a significant improvement in drivability and performance tuning capabilities.
