Mail order tunes never used WBO2. Nor do Hypertech, Superchips, Diablosport, SCT, ect.
With the AutoCal the tune can be deployed without any vehicle downtime, removal of the PCM (some customers are not comfortable doing this)
or mailing the PCM. All of that over again if a re-tune is needed.
Diablosport and SCT have similar capability BUT you have to be a dealership to put a custom tune on them.
