I once had a similar issue with a 7AL3 box. To make a painfully long story short, it turns out that the 7AL3 didn't like a 12 volt system. At least that was the story I got from MSD back in 2003 when I had the problem. The documentation that came with the box back then said that it would operate between 12 and 16 volts. But I had a miss above 5000-5500rpm that I couldn't figure out on the dyno. Sent the box back in exchange for a digital box and the problem was gone. Don't get me wrong, I'm a fan of MSD's products and I use them on everything. This just happens to be the one problem that I have had with one of their products. Take care.
