If it only goes rich at WOT that is 100% normal. That is the way our engines/ecu's are designed.
you would need an S-AFC to lean it out at WOT.

Lowering the stock fuel pressure via an AFPR might work, but you would need a Fuel pressure gauge to go with it. No one currently makes a AFPR that fits Hyundai fuel rails, so you would have to customize one.
For the expense of the customization, the AFPR and the Fuel Pressure gauge, you could have the S-AFC.
