NOTES:

• This upgrade requires you to send us your ECU one time for unlocking and tuning - Shipped back with optional Handheld Tuner for future adjustments.
• Please review our Tuning Guide below and include the ECU Tuning Information form inside the box when shipping in your ECU. We utilize this form to ensure we meet your needs and consider your modifications to deliver the best possible results.
• 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.
• You must have access to a PC / Windows computer (Mac OS not supported) to upload new tune files or reset back to stock with your Handheld device. 
• The Handheld device "marries" with your vehicle and can only be used on one vehicle.

No need to send your ECU in to return to stock - simply use the Handheld to flash back, then to your Fabspeed XperTune again at any point!
