The satin finish Victor Jr. cathedral-port single plane intake manifold houses 35 Lb/Hr injectors which are capable of 550 HP with 58 psi of fuel pressure. An all-new compact and waterproof ECU measures half the depth of the previous version. The ECU houses a faster processor, and a faster Bluetooth chip that is more reliable and will not drop connection. For plug and play convenience the ECU comes with several dyno-proven base tunes, and is self-learning, offering no-fuss drivability out of the box. For the advanced tuner, this system can also give you complete control over air-fuel ratios, ignition curve, idle speed, acceleration fuel, coolant fans, and rev limiter while retaining the simplicity Pro-Flo is known for.

The Pro-Flo 4 EFI System now comes with instructions and a QR code to download the Edelbrock App from the Apple app store and Google play store for IOS and Android. Your mobile device can now talk directly to your LS’ ECU, offering on-the-go tuning possibilities. The E-Tuner 4 features an easy-to-use setup wizard to help you get started, as well as multiple dash displays for monitoring engine vitals and performance. This EFI kit (357100) from Edelbrock pulls out all the stops for exceptional tunability and drivability.

Tech Tip: This kit will require a high-pressure EFI fuel delivery system. Fuel delivery systems are available and sold separately. This LS kit also requires a coil harness which is sold separately; your LS’ crank trigger will determine which harness you'll need. Gen III engines have the 24X reluctor design, while newer Gen IV engines have the 58X.
