When I got my car 5 years ago it has a box (beyond the MSD6al) that has retard/adv chips in it... I think they are 4deg & maybe 2 deg?? (I need to look at it again). Tell me why this adv/retard box would be used specifically... is it simply a way to adjust timing on-board?? In a drag racing scenario, when does this really benefit me? etc... do hit a button & advance it as I am towards the end of run to gain time?? It is only partially wired & i have not ever dealt w/ it. Thanks, Scooter
