I am just a messenger for this product. A lot of F-body's have the common problem with the fuel gauge reading over full when filled then dropping rapidly once it hits the half tank mark. Some also report problems like the car running out of fuel before the gauge raeds empty. This calibrator fixes these issues. As I stated I am just a messenger and I am passing this onto people who may have this problem and would be interested in fixing it for cheap. If you would like further info check out the link below or contact the actual producer of this product on the web site.
