Info
The FiTech Ultimate LS EFI kit is the ultimate LS ECU for DIY enthusiasts who want full control over their engine. Avoid having to buy additional software programs, learning how to think in computer code, or relying on a questionable 3rd party tuner. FiTech puts the engine and transmission EFI management back in your hands. The included color touch screen handheld controller allows for custom tuning adjustments to your LS engine as well as a self-learning program to get you on the road.
Leave the factory LS computer, wiring harness and intake in the junkyard where they belong. The FiTech Ultimate LS combo is a perfect match for 5.3 LS and 6.0 LS truck motors with tall and not so elegant factory intakes. The low profile fabricated sheet metal intake features short runners for a tricked out engine bay as compared to factory plastic engine covers. FiTech technology is custom cam friendly and is suitable for use with most 4.8 LS, 5.3 LS, LS1/LS6, and 6.0 LS engines with cathedral port cylinder heads producing up to 500 HP.
FiTech Fuel Injection now offers the Hy-Fuel In-Tank Retrofit Kit. You can experience the advantage of a high volume fuel system with the pump inside the fuel tank. With the pump submerged in fuel, it will run quieter and last longer. This is the easiest way to convert your existing or new fuel tank to an in-tank EFI fuel system.
