To check the tunes flashed into the vehicle, can you confirm
1. You did follow the AutoCal license/flash process as detailed here

2. You did license the ecm during the flash process. You can check license status here

3. Your tuner has validated he did send you a switchable tune, not a single tune.
4. You have tested your switch to ensure it is functional. On this point, your tuner will have needed to setup the tune to work with the switch. Other switching options exist including switching via AutoCal. You may try switching via AutoCal if your tuner has setup switchable tuning on the AutoCal menu.
