When it comes to engines, nothing gets our attention quicker than dual 4-barrels. Now, picture them as throttle bodies—and let the good times roll! FiTech Go EFI 4 2x4 dual-quad 625 hp self-tuning fuel injection systems have the ECU mounted on one of the throttle bodies, while the second holds four more injectors and the IAC motor for idle stability.

These trick systems fit Edelbrock and Holley-style manifolds without adapters, are designed for engines up to 625 hp, and can be used on tunnel or cross ram setups. They feature: a built-in fuel pressure regulator; an ECU that self-adjusts to find the best tune; and the ability to change air/fuel ratios and ignition timing on the fly.

Each system has a hand-held controller with a touch screen for initial setup, throttle linkage that suits most transmissions, and is manufactured with OE engineering. FiTech Go EFI 2x4 dual-quad 625 hp self-tuning fuel injection systems leave the guesswork behind, whether you're on the street or strip.

Additional Go EFI 2x4 dual-quad 625 hp features:

* Choice of three fuel inlet connections

* Will work with CDI box, but not required to control timing

* Adjustable fan control switch

* Can be used with an engine-mounted returnless fuel command center

* Uses easy-to-replace, GM-type sensors and Bosch 4.2 wideband oxygen sensors

* 8GB of data-logging

* Wiring harness for dual-quad installation

* Stainless steel polished linkages

* Wet-flow swirl spray annual discharge obtains complete atomization

* Systems with mounted ECUs offer spark control without the need for an external spark box or special distributor

* Voltage-controlling fuel pump control reduces power under low loads to lower temperatures

* Kit does not include linkage or fuel lines

* Designed for applications making at least 6 in. of vacuum at idle
