Hey guys I have a 2021 Kia stinger gt1 rwd with injen cold air intake secondary cat deletes and a borla catback. I recently installed jb4 with denso 1 step colder plugs gapped to 0.22 with Bluetooth and fuel wires.on map 1 when I go full throttle the car hits fuel cut and stumbles. And afr is through the roof13-15. It does this with both fuel wires installed and uninstalled. Here are the logs down before idk if there any food cause once fuel cut kicks in jb4 app freezes in phone . What can be the problem? I think maybe jb4 unit is defective.
