Custom tuning isn't just about power. At least from me its not. Custom tuning covers everything that the OTS maps does, plus the stuff the OTS map doesn't. Things like personalized throttle mapping, personalized boost curves and driving feel to name a few. There are people out there who track the cars. So they may want something catered more to their driving style for the track.

But yes, along with that, Most custom tunes will perform better from a raw power standpoint. But that just the nature of things as stated OTS mapping needs to leave a buffer of error for everything since it will be being used on many vehicles from different places, different climates, different elevations, and etc.

Fact is as good as an OTS can be, once you reach the point in your build where you want the absolute most out of your car. custom tuning is the only way to.
