Make the drive feel alive.

A premium digital exhaust system that plugs into the OBD2 port, connects in the app, and brings synchronized engine sound to the speakers.

$20 launch price. Plug it in, connect, and drive.
Built Around Real Input

Not a generic sound app.

TurboTune is built to react to the car itself. It reads live vehicle data, especially RPM, so the sound moves with the drive and gives the car a more aggressive, performance-inspired character.

  • Hardware and app working together in one product experience.
  • Synchronized engine and exhaust-style sound through the speakers.
  • Simple enough to use every day without losing the emotional part of the idea.

Easy To Live With

Keep your music. Add the engine feel.

TurboTune is designed to layer into the drive instead of taking over the whole cabin. You can still listen to music in the background and balance music with engine sound the way you want.
