Please review our Tuning Guide in the instructions above and email the ECU Tuning Information form to us. We utilize this form to ensure we meet your needs and consider your modifications to deliver the best possible results.

This is not a physical/shipped product. This upgrade requires you to send us your ECU for re-programming. You will be emailed a download link with detailed instructions after adding this to your cart and checking out.

You must fill out and include a copy of the ECU Information form along with your ECU upon sending it in. Please contact us if you need to send the form in any other manner.

Fabspeed Motorsport saves your stock/factory ECU settings so that you can revert your vehicle back to stock settings at any time.

Special requests and tune file upgrades may be subject to additional fees.
