This kit comes complete with a sleek black finish Pro-Flo XT intake manifold and 35 Lb/Hr injectors, giving you the power to reach up to 550 HP at 58 p.s.i. fuel pressure. Plus, we've included a plug-and-play single connection distributor, tailored specifically for the Pro-Flo 4, making installation a breeze.
Crafted right here in the USA, our fully terminated high-quality harness features clearly labeled connections to ensure a hassle-free setup. The new Pro-Flo 4 EFI systems are equipped with an all-new ECU that boasts a faster processor, waterproof design, and is half the depth of the previous model.
With an upgraded Bluetooth chip, you can expect faster, more reliable connections without the worry of dropouts. We’ve packed in additional features for the advanced tuner, giving you control over air-fuel ratios, ignition curves, idle speed, acceleration fuel, coolant fans, and rev limiters—all while keeping the simplicity that Pro-Flo is known for.
The heart of this system is our exclusive E-Tuner 4 app, which comes loaded with dyno-developed base calibrations. By using a Bluetooth wireless connection, the app communicates with the ECU's self-learning capability, continuously adjusting the calibration to help you achieve maximum performance. The setup wizard makes it easy to get started, and multiple dash displays allow you to monitor your engine's vital stats.
The Edelbrock E-Tuner 4 app is completely free and available for both Android and iOS devices, ensuring you have everything you need right at your fingertips.
With the Edelbrock Pro-Flo 4 XT Sequential Port EFI System, you're not just upgrading your engine; you're enhancing your entire driving experience. Get ready to feel the difference!
