Most anything you do, the engine will operate via the factory installed emission compliant program

Altering program will result in loss of powertrain warranty to original owner, and to later owner in event engine knocks / seizes and ROM cannot be found / does not match Hyundai known value

I can do mapping check, and if it been altered (tuned), it will ping Hyundai right now with details of search

 

Got it. What about modifying the wheels, tires, or suspensions? To avoid the power system.
