im wanting to dyno tune my car on 91 but people are telling me that its gonna be really expensive because apparently there is a lock on the cu and they need some kinda a license from hyundai to tune it.
is it true? and around how much would it be?

Try searching for CMD, PowerAxel, TurboXS, Beyond Redline, or Seoulful Racing. CMD is the only device YOU (or any tuner) can tune with. PA, TXS, BR, and SFR will require you to get a canned flash that's not customized for your car or to drive to their facilities and get a custom tune done so they can reflash your ECU.
