1999 GMC C3500 Fuel Injection Systems

The Edelbrock Pro-Flo 4 XT EFI Kit No. 35820 for 1986 & Earlier Small-Block Chevy engines with Vortec/E-Tec Cylinder heads has the latest technology. The EFI system comes complete with a Pro-Flo XT intake manifold and 29 Lb/Hr injectors capable of 450 HP with 58 p.s.i. fuel pressure. Also included is a plug and play single connection distributor designed to work specifically with Pro-Flo 4 and a made in the USA high-quality harness with clearly labeled connections for a hassle-free installation. The new Pro-Flo 4 EFI systems feature an all-new ECU with a faster processor, a water proof design and is half the depth of the previous ECU. It also has an upgraded Bluetooth chip that is faster, more reliable and will not drop connection. We’ve added more features for the advanced tuner giving you control over air-fuel ratios, ignition curve, idle speed, acceleration fuel, coolant fans, Rev limiter while retaining the simplicity Pro-Flo is known for. The key to the system is our exclusive E-Tuner 4 app with dyno developed base calibrations. The E-Tuner 4 app uses a Bluetooth wireless connection to communicate with the ECU’s self-learning capability to continually adjust the calibration to get the maximize performance. E-Tuner 4 features a simple and easy to use setup wizard to help you get started as well as multiple dash displays so you can monitor your engines vitals. The exclusive Edelbrock E-Tuner 4 app is Free and Available for Android and IOS based smart phone or tablet.

The Edelbrock Pro-Flo 4 EFI Kit No. 35780 for Small-Block Chevy engines with Vortec/E-Tec cylinder heads is a fully sequential multi-port injection system designed with a fuel injector strategically positioned in each runner of the intake manifold to deliver the best fuel atomization and most even distribution to each cylinder. This system features the high-performance Victor-style single-plane intake manifold that comes preassembled with high-flow injectors, fuel rails and 4150-flange throttle body. All supporting sensors are included along with wire harnesses and ECU. The Victor manifold is designed with a larger cross-sectional area in the plenum and larger runners for high-horsepower and/or large cubic-inch applications. The manifold is also 0.75 inch taller than the standard LS3 version to promote smoother airflow into the rectangular-port heads. This kit uses 29 lb/hr injectors and is rated for 450 horsepower at 58 PSI of fuel pressure. Calibration of the Pro-Flo 4 is a simple process with a Setup Wizard providing guidance through the E-Tuner application’s initial programming. Once provided with basic information such as type of engine, cubic inches, firing order, and cam profile, the E-Tuner App then selects the most appropriate base calibration. Once the base calibration is set, the self-learning E-Tuner App takes over to continually maximize the fuel map for your specific engine configuration, even compensating for changes in altitude and weather. The E-Tuner App provides more advanced tuning options that allow precise control over cold starts and acceleration while retaining the simplicity that Pro-Flo systems are known for. The exclusive Edelbrock E-Tuner 4 app is Free and Available for Android and IOS based smart phone or tablet.
