    The Most Complete Fuel Injection System Available

    Pro-Flo XT EFI Intake Manifold
    Engineering at its finest, Pro-Flo XT intakes have a large plenum and long, tapered runners to deliver maximum horsepower and broad torque across a 1500-6500 RPM range. Choose between as-cast aluminum or black powdercoating. An LS-type front-mount 90mm throttle body feeds the intake all the air it needs (only included with complete systems).

    Pro-Flo XT: The Most Complete EFI System Available
    Ready-to-run bolt-on performance packages that include:

  • Intake manifold with fuel injectors, fuel rails, and throttle body
  • Preterminated 2-piece EFI harness
  • Engine control unit (ECU)
  • Narrowband O2 sensor
  • Handheld calibration module
  • Mallory distributor
  • Fuel pump, filter, and hose
  • Installation hardware
  • Pro-Flo XT software

    Complete Wiring Harness
    Unique 2-piece design offers quick connection of the engine and chassis harness at the bulkhead on the firewall for easy removal if needed.

    Flash-Programmable ECU
    Engineered by EFI Technology, a world leader in advanced electronic engine management, this control unit features flash-programmable memory and full-sequential injection (individual injector firing). Flash memory allows multiple tuning options, including Map-N (Speed Density) and Alpha-N (Speed Throttle). Map-N references RPM (engine speed) against MAP (manifold absolute pressure) to determine fuel and spark requirements; Alpha-N references RPM against throttle position. A base calibration is preloaded, and base calibrations for common performance engines are on the included CD (additional calibrations available at www.edelbrock.com). Create custom calibrations using Pro-Flo XT software. Closed loop fuel targets with included narrowband or optional wideband O2 controller are also supported.

    Handheld Calibration Module
    Edelbrock pioneered tuning on-the-fly fuel injection in 1995 with the original Pro-Flo that featured an exclusive handheld calibration module. Also included with the Pro-Flo XT, this unique module plugs into the ECU for fast access anytime. Save up to three calibrations. An easy-to-read display allows real-time adjustment of fuel, ignition, and RPM without a computer. Initial calibration, however, must be loaded with Pro-Flo XT software on a laptop or PC.

    Pro-Flo XT Software
    If laptop tuning is preferred, use Pro-Flo XT software for unlimited custom tuning and enhanced tuning resolution of fuel and spark maps. Tune, save, and restore as many custom calibrations as you want on your PC/laptop.
