Product Overview
The FiTech 78933 Ultimate LS 1000 HP EFI Master Kit is the ultimate all-in-one electronic fuel injection upgrade designed for Chevrolet Gen III and Gen IV LS-based V8 street and performance engines equipped with cathedral port cylinder heads.

The self-tuning ECU features adaptive learning technology, built-in transmission control for GM electronic 4-speed automatics (4L60E, 4L65E, 4L80E, 4L85E), integrated 3-bar MAP sensor support for up to 30 psi of boost or nitrous, and a Go Spark 8-pack LS3-style ignition coil kit.
As a full Master Kit, part number 78933 also includes the Go Fuel In-Tank Dual Pump Module with a 2″ fill, high-pressure fuel regulator with pressure gauge, high-flow fuel rails, and flow-matched injectors to ensure consistent fuel delivery under extreme high-horsepower operation.
