I really need to hear some input from those of you who are using, or have used, these coil packs. I've got a set on now. I went for a first round of "final tuning" on my recently re-built and supercharged DOHC. On the dyno, everything drops off at around 6,000 rpm and on the road, under load, it drops off at around 5,200 rpms. We figure that I'm blowing the spark out. I was wondering if anyone had any bad experiences w/ the Screamin Demon coil packs and if I'd be better off to use my stock coil packs w/ the supercharged setup?? I'm not saying that we think these are a problem....I was just going through all the possiblities. Any help would be appreciated.
