This Go EFI Dual Quad Power Adder System Kit (1200 HP) has self-learning, an integrated ECU, (1) fan control, 4 GB data logging, a handheld touch screen tuner, 625 HP, (2) high-flow throttle bodies, and (8) precision flow injectors.
Make a statement with a pair of matte black finished throttle bodies, feeding your 671 or 871 roots blower with this 2x4 Power Adder System. One throttle body houses the ECU, while the other secures the Idle Air Control solenoid and four more injectors. This kit supports up to 1,200 HP on a naturally-aspirated engine. This system is designed to bolt onto your dual quad or blower, then fire up with a few easy inputs through the touchscreen controller. Once started, the self-learning technology will get the engine idling and cruising well; more detailed programming can be made through the advanced pro-tuning software, including fuel and timing maps under boost or nitrous.
