Edelbrock Pro Flo 4 XT EFI System Seq Port BB Chrysler RB 413-440ci 625 Max HP 35lb/hr Satin Finish

This Edelbrock Pro-Flo 4 XT EFI system is designed for Big-Block Chrysler RB-series engines, specifically the 413, 426, and 440 cubic inch displacements. What you get in this kit is a Pro-Flo XT intake manifold with a satin finish, 35 Lb/hr fuel injectors, a plug-and-play distributor that connects with a single wire, and a fully terminated wiring harness made in the USA with clearly labeled connections. This system replaces your carburetor and traditional fuel delivery with modern electronic fuel injection, offering improved performance and drivability across a wide range of Chrysler and Dodge vehicles from the late 1950s through the late 1970s, including models like the Chrysler New Yorker, Dodge Charger, and Dodge D100 Pickup.

The heart of the Pro-Flo 4 XT system is its updated ECU, which features a faster processor and a waterproof design, making it more robust and reliable. Its reduced depth also makes installation easier. The system also boasts an upgraded Bluetooth chip for a faster, more stable connection to your tuning device, eliminating dropped connections. This EFI system gives you advanced control over critical engine 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 is tuned using the free E-Tuner 4 app, available for Android and iOS devices, which connects wirelessly via Bluetooth. This app includes dyno-developed base calibrations and a setup wizard to help you get started, allowing the ECU to self-learn and continually adjust the calibration for maximum performance. You can monitor engine vitals through various dash displays within the app, and importantly, no laptop tuning is required.

The 35 Lb/hr injectors included are rated to support up to 550 horsepower with 58 p.s.i. of fuel pressure. For those who prefer a complete package, Edelbrock also offers kits that include a 7-inch Android tablet with the E-Tuner 4 app pre-installed. This system is a significant upgrade for anyone looking to modernize their classic Mopar big-block, offering a blend of advanced tuning capabilities and user-friendly operation.
