Sports Cat no tune 2021 M340I UK
Is anyone here running on their 2021 M340I a sports cat or de cat with no tune.
Have had the GPF/ OPF removed and coded out and next step is a sports cat and intake modes for stage 2 next year but I don’t want to unlock and tune. Anyone been able to run a sports cat on stock software safely ? No CEL? |
