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!
