  • Adds up to 17hp & 20ft-lb .
  • Easily plugs into the stock ECU & ECU harness in minutes , no programming necessary .
  • Realizes the full potential of Aftermarket add-on’s like Cold-Air-Intakes & exhaust systems , as each kit comes pre-mapped for the exact set-up of each car or truck.
  • No end-user tuning necessary , just plug the kit into the car & you’re ready to go.
  • Easily upgradeable for future add-on’s.
  • Each kit comes with two maps : a low octane performance map & a high octane performance map, switchable from within the vehicle.
  • Fully tuneable by a Unichip Custom Tuner for customized add-on’s . This basically means that the Engine Management System in your ride is now as tuner friendly as the most advanced Standalone systems in the world , without sacrificing any of the factory features. This feature is unmatched by any reflash-tuning or other similar product.
  • Plug ‘n Play harnesses are fully Flux capable – purchase Flux when you purchase the Plug ‘n Play kit or upgrade later – Flux simply plugs into the Unichip Plug ‘n Play harness.
  • Plug ‘n Play kits are removed from the vehicle in minutes , returning the vehicle to stock tuning , without leaving a footprint of ever having been modified (a feature which reflash-tuning cannot match).
