    MHD crackle tune on custom tune

    Hello people on Spool Street, my name is Mario. I have a beautiful stock 135i with a Custom Tune pushing around 360 wheel, and i was wondering if its possible to still run my custom tune and have the MHD crackle tune enable without any issues. If anyone have any idea on how this could work/...
