    FiTech Go EFI 2x4 Dual-Quad 625 hp self-tuning fuel injection systems with Force Fuel provide steady fuel to keep your Sunday cruiser, classic, or race car running under the most extreme conditions.

    Dual-quad EFI systems handle up to 625 hp and feature a four injectors on each throttle body. They have the ability to change air/fuel ratios and ignition timing on-the-fly. You have the power of a hand-held controller with a touch screen for easy setup and adjustments. Thanks to a multi-bolt pattern, the 2x4 system will bolt onto most intakes, including tunnel rams, cross rams, Edelbrock, Holley, and many factory-style intakes.

    FiTechs all-new Force Fuel system makes the upgrade to FiTech EFI even easier! It mounts under the hood and is fed with the original mechanical or electric fuel pump. The fuel pump then fills the reservoir with a half-gallon of fuel to submerge an internal electric fuel pump—to keep it cool for long life and no chance of fuel starvation. An internal regulator keeps the pressure at a consistent 58 psi. Force Fuel then supplies the EFI system with the required high pressure to run at peak performance.
