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!

Zero stars
Size: 1 Panel, Color: Black
The bars are impossible to screw in all the way so it’s not sturdy at all, trash and waste of time

Great product, sturdy and well made. Easy assembly.
Size: 3 Panel, Color: Beige
These are awesome! They were easy to assemble. They are lightweight and easy to move. I was able to easily put all 6 pieces -(I ordered two sets)-into the back of my SUV at once, by myself (and I'm a short, older lady). Quality material. Very sturdy and steady. The first set I opened was a used one and did not include instructions, but it was still very easy to assemble and figure out. I recommend using a battery powered screwdriver. With that, the assembly of all 6 panels took less than 45 minutes.

Defective product

All screws cannot fit with each connectors. The Allen key provided is useless because it doesn’t fit into screws.

Love it, happy with the price
Size: 1 Panel, Color: Black
I have been using this product for a month now. I'm absolutely thrilled with my new Room Divider. It's has made a significant difference in my home. The divider is not only stylish and well-crafted but also incredibly functional. It has effectively separated my open space into cozy, distinct areas, enhancing privacy. Assembly was a breeze, and it's built to last. This room divider has truly transformed my living space, and I couldn't be happier.
