Tune Features

This is a Custom Off-The-Shelf (OTS) calibration, not a fully custom tune. It has been specifically developed to improve the factory calibration while maintaining excellent drivability and reliability.

• Reduced false knock events
• More precise boost control
• Increased rev limiter to 6,400 RPM
• Optimized throttle response
• Improved MAF scaling
• Full FAST WC remap that provides greater power and responsiveness than the standard COBB OTS calibration

Compared to the standard COBB OTS map, this calibration typically produces 10–20 additional wheel horsepower, and approximately 40–50 wheel horsepower over the factory calibration, depending on fuel quality, environmental conditions, and vehicle condition. Drivers can expect significantly improved throttle response, smoother power delivery, and a noticeable increase in overall performance.

Important Information

This purchase includes a COBB ProTuning calibration file only.

This is an Off-The-Shelf (OTS) calibration. No data log reviews, custom tuning, revisions, or map adjustments are included with this product.

If you install additional performance modifications in the future that require recalibration, FAST WC offers a discounted upgrade to a full custom protune.

Your vehicle must be in good mechanical condition before purchasing or installing this calibration. FAST WC calibrates the tune only for the modifications selected during checkout. Vehicles with existing mechanical or electrical issues are not eligible for refunds, and FAST WC is not responsible for diagnosing or repairing pre-existing mechanical or electrical problems.

All sales are final.

Installation Notes

Before installing your calibration, update your COBB Accessport to the latest firmware.

If the Accessport displays a message indicating that the calibration does not match the installed vehicle firmware, simply select “Yes” to continue. The Accessport will flash the ECU normally and update the ECU firmware automatically during the installation process.
