2004-2021 Subaru WRX STi Remote Tune w/ Cobb AccessPort

Our custom remote tune for 2004-2021 Subaru WRX STi utilizing a Cobb Tuning AccessPort is one of the best ways to increase power safely without sacrificing driveability. Select Single Map for one fuel type only (91 oct/93 oct/E85), or select the Dual Fuel Maps option for two seperate fuel types or Flex Fuel Tuning. You can choose any two fuel types for the separate maps. Flex Fuel requires the Cobb Flex Fuel Kit. The Cobb Fuel Pressure Differential Kit is also highly recommended for Flex Fuel, but not required. Ethanol tuning requires larger injectors and fuel pump. Please select the setup options that best suit your build, and your wants/needs. Your setup may be subject to additional charge once full modification list has been verified.

Will require AccessPort number (ex: SUB0436555), and full modification list upon purchase. You will be sent a base calibration file based on your vehicle, modifications, and fuel type via email. We then require you send all requested data logs back via email, and we will continue to send you revised files until your calibration appears perfect over datalogs and any possible calibration issues have been addressed. We recommend all remote tunes go through the Pre-Tune Checklist prior to tuning to verify everything is ready for the tuning process. We are not responsible for any issues that arise due to underlying mechanical issues or mechanical failures.

Feel free to message our Facebook or Instagram page, or email stew@roguearttuning.com if you have any questions prior to the tuning process.
