NOTES

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.
