I have been reading horrible reviews on MSD quality lately. I was planning on running Digital 6 on my 13.5:1 496 w a single stage plate. What alternatives are out there that work? I have only run HEIs in the past so I don't have any experience with boxes. I really like the features of the digital 6, start retard, single stage retard, and built in rev limiter. I have an MSD billet dist if that matters.
