To be honest....I'm not sure of the brand, I'll have to look. Didn't really pay attention when I had it out to do the intake manifold, as I needed to get the truck back together asap. I've kinda been leaning toward a dist problem, as it seems to me that the problem feels like the timing being retarded. But the ecm itself is calling for the correct timing, so that leaves the dist. What aftermarket brand were you using?
