Part II of my everyday series of videos chronicling upgrades and the everyday use of my M3.

This video illustrates the everyday tractability of the ss91 Iigo chip and 276/264 cams. Nice gain in torque between 3000 and 6000 rpm. Little bump in top end. Great idle too. Will probably gain up top with an afm delete or standalone; and acquiring a real 276 cam, not just a regrind (more lift).
