Info

The Ultimate LS 750HP Kit without trans control for LS1/LS2/LS6 are a complete self-tuning induction systems for LS engines designed for the do-it-yourself hot rodder to the professional EFI tuner! This system is ready to go with everything needed to complete the induction system of your LS engine and get you on the road easily and faster than any system on the market today. Forget sourcing mismatched parts and cutting and splicing old harnesses and re-flashed ECU’s from “Craigs List” tuners. The Ultimate LS1/LS2/LS6 750HP Kit combined with the Command Center 2 fuel delivery kit includes everything you need for installation.

FiTech Fuel Injection’s Go EFI Command Center 2 is the ultimate answer to fuel system simplicity! Designed to be used in vehicles with stock fuel tanks converting from carburetor to EFI. The Command Center 2 eliminates that problem. Complete new design from years of testing has resulted in the most effective system anywhere. The pump in the Command Center 2 never gets uncovered because it receives a steady supply of fuel from your existing fuel system. So your system maintains a constant flow of fuel. The built-in regulator eliminates the need for an external regulator. Since the Command Center 2 is constantly circulating fuel to and from your tank, your fuel pump stays cooler and will have a longer life. The fuel pump noise is also muffled by being submerged in fuel 100% of the time. The Command Center 2 is the best way to provide the necessary increase in volume when adding a power adder such as boost or nitrous to your engine. So, whether you are racing, off-roading, or just cruising, this “compact” external fuel assembly is your all in one solution.
