Elevate your 1999 Mustang GT to new heights with our Tuner Kit, designed specifically for the V-2 Si engine. This polished finish kit is a game-changer, offering a significant boost in both horsepower and torque. With the ability to safely increase your GT's horsepower from 260 to 364 and torque from 302 lb./ft. to 371 lb./ft., you'll experience a thrilling driving experience. The kit is available with a V-3 internally lubricated supercharger, providing even greater performance gains.

High-Output Supercharger Systems with Advanced Features

Our Tuner Kit features a high-output supercharger system that takes your Mustang GT's performance to the next level. The system includes a fully integrated air to water aftercooler approach for charge cooling, increasing horsepower from 260 to 402 and torque from 302 lb./ft. to 400 lb./ft. This advanced system requires a battery relocation kit (sold separately). Key features of the kit include a Vortech gear-driven supercharger with SQ technology for silent operation and unmatched reliability, a high-efficiency impeller and housing design, and a fuel management upgrade with a high-flow fuel pump, high-capacity fuel injectors, and an EDM Chip. The integrated air/water, dual-pass charge cooler configuration allows for additional horsepower gains and features a maintenance-free design.

Installation and Compliance

Our Tuner Kit is designed for those who want to take their Mustang GT to the next level, whether for racing or daily driving. The installation process is approximately 12 hours, making it a manageable upgrade for the DIY enthusiast. It's important to note that this Tuner Kit is not CARB legal and is intended for off-road use only in California. For those looking to customize their fuel system and ECM reprogramming, this kit offers the flexibility to do so. With Vortech's supercharger options for various types of racing and boost levels, this kit is perfect for tuners and racers seeking peak performance.
