2g dsm sputters and only makes 5lbs. No boost leaks. Help

Positive there are no leaks. Went from 30 to 12lbs over 45 seconds. Plugs are new Ngk bpr7es gapped to .024. I'm running a coil on plug setup that was a home made setup. I heard that could be the issue, so I'm switching over to a sparktec cop. I don't have a dis or arc2 yet, but I read that that's shouldn't be an issue at this low of boost. Thoughts?
