If you’re doing an LS swap, the Edelbrock (35993) Pro-Flo 4 XT Sequential EFI System for Chevrolet LS Gen III/IV engines makes the process simpler. This kit offers wireless tuning through your compatible mobile device, and support for up to 550 horsepower.

Features and Benefits:
- Sequential Fuel Injection system
- Capable of 550 horsepower
- Complete tuning control
- App-based tuner connects to ECU wirelessly
- Waterproof, compact, and self-learning ECU

The black Pro Flo XT rectangle port 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 the connection. For plug and play convenience, the ECU is easily programmed with one of 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 Pro-Flo simplicity.

The key to the system is Edelbrock’s exclusive E-Tuner 4 app. Your mobile device can also 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. Best of all, the E-Tuner 4 app is free and can be downloaded from the Google Play Store or Apple App Store, allowing you to use your personal android or IOS device. With an XT style intake, high flow injectors and convenient tuning options, this Edelbrock (35993) EFI system will take your LS swapped project car to a whole other level.

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.
