    Is the remap done by a software replacement or a “box”? If it’s a box, try to unplug it to see if the problem disappears.

    Any trouble codes?
    You can also check for all values of the sensors to see if there is any strange values due the warmup.

    If you have a diagnostic computer, you should check the values of the coolant temperature sensor while it’s running rough, also check for fuel pressure and pump timing. But because of the software edit, it could be a bug in that software.
