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.
The HyperFuel Single Pump G-Surge Tank is designed to be used in vehicles that have fuel starvation issues when being used in extreme lateral G-force environments. Typically, this is due to poor fuel tank baffling in the existing fuel tank. The G-Surge eliminates that problem. The pump in the G-Surge never gets uncovered because it receives a steady supply of fuel from your existing fuel system as well as the fuel returning from the fuel injection system. So your system maintains a constant flow of fuel. Since the G-surge 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 G-surge is also the best way to provide the necessary increase in fuel volume when adding a power adder, such as boost or nitrous to your engine.

Now that Project Chevelle is making some real power, we've decided to ditch the old tank, lines, and pump in favor of a new tank and pump from Tanks Inc.
