    • Msd 6al-2 dead

      I got in the mail at 4:20 or so. And the box is installed, and not turning on. I called msd we trouble shot it for a bit and found the box it dead. Lucky msd is emailing me a shipping label to sent the unit to them.

      Works will like any MSD product. Love being able to change the idle and two step by a turn dial. No need to change chips. Would recommend to anyone
