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!
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 for a small fee.
Shipping costs for sending an ECU to Fabspeed is the responsibility of the purchaser. The ECU will be tuned within 24-48 hours of receiving it and Fabspeed will then ship back the ECU using whatever method it was shipped in with. (For example: If you send in your ECU via Ground shipping, we will ship it back via Ground. If you ship it via Overnight, we will ship it back via Overnight.)
