Autotronics (MSD) seems to have many problems that could be fixed by better management of design and operations. GM tuners have had many failures with their very expensive upgraded LS coils (>$600/set). I have heard similar of their more standard offerings. As one small data point, my company ordered an MSD box specially configured to self-pulse for a non-automotive application. They sent us a regular box and the special box to a regular customer. We never heard if that blew up some drag racer's engine. However, I don't know if Accel, AEM, or others are much better. Many horror stories out there.
