Totally my fault, I remember tightening it on the dyno but didn't use Loctite, just the little spring washer. Won't make that mistake again. I truly believe now (might be wrong) our old headers would cure the issue of pulling down low, they also might cause a horsepower problem up top though too. Maybe I just need some collector extensions, testing will sort all this out. We'll probably put some new plugs in it and swap headers for Rockingham to see what it does.
