If you own a 1986 or earlier Small-Block Chevy with Vortec/E-Tec cylinder heads, the Edelbrock Pro-Flo 4 XT EFI Kit #35823 is just what you need! This kit is packed with cutting-edge technology to give your engine the performance it deserves.
The EFI system includes everything you need: a Pro-Flo XT intake manifold and 29 Lb/Hr injectors that can handle up to 450 HP at 58 p.s.i. fuel pressure. Plus, you’ll receive a plug-and-play single connection distributor that’s specifically designed for the Pro-Flo 4 system, making installation a breeze. Our high-quality harness, made right here in the USA, comes with clearly labeled connections to eliminate guesswork.
The new Pro-Flo 4 EFI systems feature an innovative ECU with a faster processor, a waterproof design, and a compact size that’s half the depth of its predecessor. The upgraded Bluetooth chip ensures a speedy and reliable connection, so you won’t have to worry about interruptions.
For those who love to tinker, we’ve included advanced tuning features that allow you to adjust air-fuel ratios, ignition curves, idle speeds, acceleration fuel, coolant fans, and rev limits—all while keeping the user-friendly experience that Pro-Flo is known for.
The heart of this system is our exclusive E-Tuner 4 app, which comes with dyno-developed base calibrations. This app connects wirelessly via Bluetooth to the ECU, allowing it to self-learn and continually optimize your calibrations for maximum performance. With a simple setup wizard and multiple dash displays, monitoring your engine's vitals has never been easier.
The Edelbrock E-Tuner 4 app is free and compatible with both Android and iOS smartphones or tablets, making it accessible for everyone looking to enhance their driving experience.
