Edelbrock Pro Flo 4 XT EFI System Seq Port LS Gen III/IV Cathedral Port 550 HP Max 35lb/hr

Starting with the Pro-Flo XT cathedral port intake manifold, this Edelbrock Pro-Flo 4 XT EFI System is built for Chevrolet LS Gen III and IV engines. It features 35 Lb/hr injectors that are rated to support up to 550 horsepower with 58 p.s.i. of fuel pressure. This system is designed to fit a wide range of vehicles, including models like the Chevrolet Silverado 1500, Cadillac CTS, and Pontiac GTO.

At the heart of this system is a new, compact ECU with a faster processor and a waterproof design. It also boasts an upgraded Bluetooth chip for a more reliable and faster connection to your tuning device. For those who like to fine-tune, the system offers advanced control over air-fuel ratios, ignition timing, idle speed, and cooling fans, all while maintaining the user-friendly simplicity that Pro-Flo systems are known for. The system doesn't require a laptop for tuning; instead, it uses the free Edelbrock E-Tuner 4 app, available for Android and iOS devices, which connects wirelessly via Bluetooth. This app includes dyno-developed base calibrations and a setup wizard to get you started, plus multiple dash displays to monitor engine vitals.

The E-Tuner 4 app's self-learning capability continually adjusts the calibration for maximum engine performance. You can download the app from the Google Play Store or Apple App Store. Edelbrock also offers kits that include a 7-inch Android tablet with the E-Tuner 4 app pre-installed if you don't have a compatible device. This EFI system is a comprehensive upgrade for LS engine owners looking for improved performance and modern fuel injection technology.
