Features
Vehicle Compatibility and Return Conditions.
This item was designed and engineered in the USA for US domestic vehicles. OBD tools, ECUs, dongles, programmers, and tuners may have limited compatibility with vehicles outside the USA due to regional differences in emission standards and system configurations. Some features and functionality may vary depending on the vehicle and location.
Some electronic tuning devices and programmers require activation, registration, or pairing with a specific vehicle’s VIN (Vehicle Identification Number). Once activated or paired, these devices may become permanently associated with that vehicle, restricting or preventing their use on another vehicle, resticting our ability to offer returns or exchanges.
Please review the product details and images to ensure it meets your needs. For clarification or assistance, feel free to contact a StreetFX agent. Note: Returns are not accepted for special order or tuning products unless the unit is deemed faulty.
Images are supplied by the manufacturer and may be generic. While all efforts are made to provide accurate pictures, there may be differences in the actual product, such as colour, quantity, version, or included components. Please carefully review the description and specifications for details on inclusions or any variations. Some items may be sold individually or in sets, and images may occasionally depict additional products or quantities not included in your purchase.

LS motors have a great base for power, but what they really need is something wicked to wake them up. FiTech LS EFI 750 HP fuel injection systems have alarming power, exciting style, and will take you and your vehicle to the edge. FiTech fabricated many aluminum parts for these systems, including the low-profile 102mm billet throttle body, high-volume billet fuel rails, and an intake manifold with a 1,500 to 6,500 rpm powerband and 3mm construction.
Sequential spark and fuel control mate the 55 lbs./hr. injectors, plug-and-play wiring harness, and color touch screen self-learning ECU. This allows you to program two fan control outputs, most tach and speedometer output drivers, and target AFR and timing on-the-fly. A suction cup mounting bracket puts the controller at your fingertips and allows for impressive visual aids.
The optional transmission control feature is suitable for 4L60, 4L65, 4L70, or 4L80 GM transmissions. Awaken the beast and feed its needs with an ultra-performing FiTech LS EFI 750 HP fuel injection system with transmission controller.
