Unleash the "Rally Soul" of Your Subaru

Love. It's what makes a Subaru a Subaru. Now, add some adrenaline.

You bought your Subaru for its legendary Symmetrical All-Wheel Drive and its go-anywhere capability. Whether you are carving canyons in a WRX, traversing trails in an Outback Wilderness, or navigating the daily commute in a Crosstrek, you know the chassis is world-class. However, the factory tuning—specifically the "rubber band" feel of the CVT and the conservative mapping on the Boxer engine—often leaves you wanting more punch when you merge or climb steep grades.

The Stage 3 "Rally-Spec" Performance Module is the upgrade your Boxer engine deserves. Engineered to optimize both the **Naturally Aspirated** and **Turbocharged** platforms, this OBDII module sharpens the throttle response, reduces CVT lag, and unlocks the torque you need to carry your gear, your family, and your sense of adventure.

✔ Fix CVT "Rubber Banding". ✔ Wake Up the Crosstrek/Forester. ✔ Boost WRX Response.

Why Upgrade to Stage 3?

• The "Crosstrek Cure": The #1 complaint of Crosstrek and Forester owners is sluggish acceleration. Safely unlock up to +30 Horsepower and +35 ft·lbs of Torque to make merging onto the highway safe and effortless.
• CVT Optimization: The Lineartronic CVT is efficient, but often hesitant. We optimize the torque signal to help the transmission hold "virtual gears" better, reducing the droning noise and providing a more direct, engaging drive.
• Turbo Spool (WRX/XT): For WRX, STI, and Outback XT owners, the chip reduces turbo lag, allowing the boost to hit earlier in the RPM band for that classic "seat-of-the-pants" rally feel.
• Adventure Ready: Added low-end torque is essential when you have a roof box, a bike rack, or a trunk full of camping gear. Climb mountain passes without the engine screaming at 5,000 RPM.
• Universal Star Cluster Compatibility: Works seamlessly with the Outback, Forester, Crosstrek, WRX, STI, Legacy, Impreza, Ascent, and BRZ.
• Plug & Play Adventure: Installs in under 60 seconds via your OBDII port. No tools, no mechanic, and no permanent ECU flashing.

Smart Tuning for the Boxer Engine

The Subaru Boxer engine is unique. The Stage 3 Tuner uses adaptive logic to enhance its low center of gravity performance.

The Non-Turbo Solution (2.0L / 2.5L): These engines are bulletproof but can feel underpowered. Our module advances the ignition timing in the mid-range, giving the car a "second wind" when you need to pass slow traffic.

The Turbo Strategy (FA20 / FA24 / EJ25): For the performance models, the chip sharpens the throttle mapping to mitigate the factory "rev hang" and optimizes boost pressure for a sharper, more aggressive drive.

100% Safe, EyeSight Compatible & Reversible

Safety is a Subaru priority. The Stage 3 Performance Chip is 100% safe.

EyeSight Safe: This module works independently of the EyeSight driver-assist system. Your adaptive cruise control and lane-keeping assist will function perfectly—you'll just have more power when you need it.

Warranty Friendly: The device operates as a piggyback system. It does not permanently rewrite your ECU. If you need to visit the dealership for service, simply unplug the unit. Your Subaru returns to stock factory settings instantly.

Frequently Asked Questions

Will this work with X-Mode?
Yes. X-Mode alters the traction control and throttle sensitivity for off-road use. The chip works in harmony with X-Mode, providing steady, consistent torque that helps you crawl over obstacles without unexpected surges.

Does it help with the "Rev Hang" on manual WRXs?
Yes. One of the biggest complaints on the WRX is that the RPMs stay high when you push in the clutch. By sharpening the throttle signal cutoff, the chip helps the RPMs drop faster, allowing for smoother, quicker shifts.

Is it compatible with the Outback Wilderness?
Absolutely. The Wilderness has lower gearing for climbing. The Stage 3 chip adds the torque to match that gearing, making it an absolute beast on steep inclines and soft sand.

Is installation hard?
It is effortless. The OBDII port is located under the dashboard on the driver's side (usually near the hood release). Simply plug it in. It takes less than 60 seconds.
