was in super chips yesterday getting my leon cupra stage 1'd and i'm pretty sure the bluefin locks itself to one car, if you un install it from your current car and get the bluefin reset which i believe is around 180 pounds plus vat then you can us it on another car. I had the bluefin on a scirocco and when i sold the car i didn't remove the super chips remap so when i went back into super chips yesterday they could see i hadn't removed it and i had to pay the full 320 pounds for the new map. was worth it though
