BOOST YOUR SUBARU WRX

The Subaru WRX has a cult status in the rally scene, and a strong following in the tuner world. A competition-bred icon known for its all-wheel drive excellence, it’s built to grip, rip, and send it through any road, any season, any time. It’s the go-to ride for speed demons and trackday junkies. But let’s be real. The stock drive-by-wire throttle feels slow.

The fix? The FN Tuned throttle response controller. Kill that annoying lag and tap straight into your WRX’s raw turbocharged power. With four adjustable driving modes and 36 fine-tuning levels, you can dial in the perfect setup for carving up backroads, dominating the track, or just tearing up the streets. Plug-and-play, Bluetooth-controlled, and 100% untraceable, this is the upgrade your WRX needs to have!

FN Tuned Throttle Response Controller for Subaru WRX

Install in 15 Minutes. No Tools Needed.

  • ✔

    Turn off your vehicle and keep the key fob at least 35 feet away. This prevents the key fob from triggering the ECU, ensuring a complete electrical shutdown.

  • ✔

    Locate the pedal position sensor (usually behind or at the top of the gas pedal assembly) and unplug the factory connector.

  • ✔

    Connect the male and female ends of the FN Tuned harness to the corresponding sockets. Ensure you hear a “click” each time.

  • ✔

    Secure the FN Tuned module somewhere in the footwell area with the included zip ties, make sure the module or the wiring does not block any moving parts.

  • ✔

    Activate your unit using the mobile app.

Start ripping!
