Just picked up an MSD DIS-2 (62112). The instructions make mention of using the step retard wired in with nitrous but make no mention of a retard for boost, but if I'm reading this right the 1st dial should be set to 1 the 2nd to 0 the 3rd to 2 (for 2 deg. of retard, 3 for 3 deg. and so on) and the 4th - 7th set to max. This post is aimed at Rodimus, seeing as he usually has the MSD answers.
