The Edelbrock Pro-Flo 4 XT EFI Kit #35923 for Chrysler big-block 413, 426, 440 RB engines 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 a black powder-coated Pro-Flo XT manifold that comes preassembled with high-flow injectors, fuel rails and 90mm throttle body. All supporting sensors are included along with wire harnesses, ECU and Android-based tablet with E-Tuner Calibration app pre-installed. The high-performance Pro-Flo XT manifold is designed with a large plenum and long tapered runners for high-horsepower and/or large cubic-inch applications. This kit uses 35 Lb/Hr injectors and is rated for 550 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?s initial programming. Once provided with basic information such as type of engine, cubic inches, firing order, and cam profile, the E-Tuner then selects the most appropriate base calibration. Once the base calibration is set, the self-learning E-Tuner takes over to continually maximize the fuel map for your specific engine configuration, even compensating for changes in altitude and weather. The E-Tuner 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. No laptop tuning is required.
