Not sure if anyone else has experienced this issue. Follow all instruction, calibration tool runs diagnostic, you backup the VIN & data, then when you get to the part where you submit the voucher code, it tells you, "The Voucher ID has already been activated. Please confirm your ID and try again". Very frustration since the ST is at the dealer and I will need too contact Ford Performance now......
