If you're looking to upgrade your Big-Block Chevy Oval Port engine, the Edelbrock Pro-Flo 4 EFI Kit #35840 is just what you need. This kit is packed with cutting-edge technology and features designed to bring out the best in your ride.
The EFI system comes complete with a traditional 4150-style single plane intake manifold and powerful 60 Lb/Hr injectors that can handle up to 825 HP at a fuel pressure of 58 p.s.i. You’ll also receive a plug-and-play single connection distributor, specifically made for the Pro-Flo 4, along with a high-quality, fully terminated wiring harness that’s made in the USA. Each connection is clearly labeled, making installation a breeze!
We’ve upgraded the Pro-Flo 4 EFI system with a brand-new ECU that boasts a faster processor and a waterproof design, all while being half the depth of previous models. The enhanced Bluetooth chip ensures a speedy and reliable connection, so you won’t have to worry about dropouts.
For the advanced tuner, we’ve packed in even more features. You’ll have complete control over air-fuel ratios, ignition curves, idle speed, acceleration fuel, coolant fans, and the rev limiter, all while keeping the user-friendly simplicity that Pro-Flo is known for.
The heart of the system is our exclusive E-Tuner 4 app, which comes with dyno-developed base calibrations. This app uses a Bluetooth wireless connection to tap into the ECU's self-learning capabilities, continually adjusting the calibration for optimal performance. The setup wizard is straightforward, helping you get started in no time, and you can keep an eye on your engine’s vitals with multiple dash displays.
The best part? The Edelbrock E-Tuner 4 app is completely free and available for both Android and iOS smartphones or tablets. Get ready to take your Big-Block Chevy to the next level with the Pro-Flo 4 EFI System!
