Replace your carburetor with a "Bolt on and Go" TBI system that also allows you to tune as well HP EFI throttle body kits are a direct replacement for a square flange carburetor. Plug and play connectors make installation a snap and by utilizing a laptop (or the optional 5.7" full color touch screen LCD) along with the HP's self-tuning capabilities, you will be up and running in no time. Come with most all parts necessary for a complete installation including throttle body, ECU, wiring harness and sensors. Fuel pump available separately to fit your requirements.

Holley HP EFI systems are equipped with 4 programmable inputs and 4 programmable outputs that are ideal for most vehicles with a single power adder. This feature allows the user to configure the system to support a wide range of controls including boost control, progressive nitrous, water/meth injection, speed inputs, fuel pump control, AC inputs, timing retard inputs and various other uses. When selecting an ECU, users need to ensure their planned controls can be run with the 4 inputs and 4 outputs as certain combinations may use more I/Os than are available. If more I/Os are required, users should choose the Dominator VMS.
