Indeed...and even then, I'm not sure either the M2 or the M135i are necessarily the best tool in the box for drag racing...even when modified.

Both, however, offer significantly more launch than the F30 328. Also, pay close attention to what the various tunes actually offer. It's easy to boost the T6 power, but there can be reliability issues unless there's associated fueling and timing maps.
