Recently just purchased a used 21 stinger 3.3. Have come to realize it has been back end tuned. Cannot find any markings on the ecu or tcu, but rev limiter has been raised. Being that it has been tuned before but cannot figure out who tuned it, how can I fix this? I would like to be able to tune it, but what would be the best way to overwrite the existing tune file? Can any tuner even get into it if it has been tuned prior and not returned to stock files? Newer to this but have some experience, nothing with kia tho.
