This bundle includes the Cobb Accessport V3 Device!
The only Subaru WRX tune on the market with linear DAM scaling between 89 and 93 octane!
Put the vape down because you'll need both hands cornering your WRX after flashing the Monster Tuned Stage-X tune! Experience awesome gains of 109 HP over stock on premium fuel or up to 144 HP over stock on E50 fuel.
Our tuning strategy is to produce a calibration that can adjust for fuel quality, modifications, and offers OEM reliability.
On our 2024 development WRX we discovered that the factory tune is riddled with false knock events, and unreliable DAM to the point where we experienced a -7 knock correction simply backing out of the garage with stock tune. You can't build an octane learning tune with an unreliable knock system. To tackle this issue we put the WRX through over a 1,000 hours of drive cycles, and 300+ ecu flashes on high octane fuel to identify specific cells that were problematic and make the knock learning system more reliable. Additionally we found the stock tune actually experiences real knock between 1,000-2,000 rpm going up hill when engine loads are between 0.93 and 1.09. These knock events were quite large and and can be seen when running the stage 0 map on the cobb accessport.
The Stage-X tune reworks the OEM DAM logic to make it predictable and offer linear scaling between lower and higher octane fuels. This results in a tune always optimized for the fuel that you're running and providing the best results.
One of the largest benefits of Stage-X is that you can continue to modify your vehicle with out changes to your calibration. Stage-X will support most bolt on modifications and when a part is changed you can re-flash the calibration or perform a KAM reset using the cobb accessport so that the vehicle can re learn turbo and airflow parameters stored in the KAM table.
Important! The Subaru WRX uses a MAF sensor to measure airflow. Tune updates are required after changing the intake!
All Stage-X calibrations are emissions compliant and will pass emissions testing. Removing or tampering with emissions equipment on your vehicle will result in a check engine light and the vehicle failing an emissions test.

What kind of power should I expect?
The power that you get will be heavily dependent on cooling and fuel quality. We highly recommend an upgraded intake with a closed airbox to achieve advertised power results. Higher intake air temp (IAT) will reducing power and limit maximum allowed torque.
Power figures will vary depending on fuel quality and are measured at the wheel.
- Stock: 271 HP
- 91 Fuel: 365 HP
- 93 Fuel: 380 HP
- E50 Fuel: 415 HP
Driving Tips
For fastest acceleration the optimum shift points on our tunes for peak power is 5800 rpm. Shifting later than this will result in slower acceleration.
*** Ethanol Mix Notes ***
The 22+ WRX gas tank is 16.6 gallons. For our E50 WRX tunes we require mixing 8.3 gallons of e85 (E70-E90) to a full tank of 91/93 octane fuel. For future fill ups after the initial mix use a 50/50 ratio of e85 and 91/93 fuel.
When mixing always allow 15 miles of driving for the fuel to mix before going wide open throttle. Failure to allow the fuel to properly mix can result in excessive knock.
For E85 pumps that do not state an e70 minimum statement we recommend testing your fuel at least once a month using an ethanol test kit.
