What do I need and what do I don’t!

The older made in the U.S.A msd boxes are good. If it is made in China,I would be worried.
It's the newer digital boxes, too. Like what are being made right now. With good parts still available for the Mopar ignition, I'm just not a fan of MSD. Never have been. I think the Chevy crowd is responsible for that epidemic and most of their stuff is slow.
