22-25 WRX Stage-X (Tune Only)

What is Stage-X and what makes it better than the competition?

Our Stage-X line of calibrations are essentially an improved version of the OEM Subaru WRX calibration. We start from the OEM stock map and increase the vehicles ability to target higher engine loads/torque at wide open throttle. The result is a calibration that maintains 100% stock OEM feel and reliability, but maximum power that the car is capable of at wide open throttle. Despite being significantly safer than competitor maps, our calibration allows for maximum power possible, and typically outperforms competitor calibrations.

Stage-X calibrations are federal emissions compliant and will pass federal emissions testing (Not CARB approved). Removing or tampering with emissions equipment on your vehicle will result in a check engine light and the vehicle failing an emissions test like the oem calibration.

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 of our Stage-X calibrations drive as smooth as stock with improved turbocharger response during throttle in conditions as well as offering a driving experience unlike anything offered by the competition.

Supported vehicles:

• 22-25 wrx manual
• 22-25 wrx cvt

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: 253 WHP
• 91 Fuel: 315 WHP
• 93 Fuel: 325 WHP
• E50 Fuel: 375 WHP

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.

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.
