Performance improvement with RaceChip tuning chip. - Model Name: RaceChip GTS Black Connect - Type: Tuning chip - Number of Connectors: 3 - Power Supply Method: Connected to the vehicle's OBD-II port Since it's the GTS Black Connect, it can be operated from a smartphone. Please check the photos for compatible vehicles. Removed from an Audi TT. I used it without considering resale, so there are some scratches. There is also some adhesive residue from the double-sided tape. It was working without any problems until I removed it six months ago. Please contact the manufacturer for installation and usage instructions. The box looks good in the photo. It looks a bit more worn in person.
