NOTES
- 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.
- Upgraded at no charge by Fabspeed over the life of the car. Can be flashed back to stock when you would like at any time.
- While a vehicle equipped with bolt-on upgrades will experience maximum gains as a result of the increased efficiency of the engine, great power gains can be made on a completely stock vehicle!
- 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.
Enjoy your increased performance!
