when you boost leak tested it did you open the throttle body?

I'll try unplugging the IACV next. BOV is atmospheric, but I dont think that's the problem. Only running like 7lbs of boost. I have a grounding kit installed, so grounds should be good, and I had the battery and alt checked out not too long ago, but it wouldn't hurt to double check. Just changed the plugs recently, so I'm gonna leave em in til I can get this figured out
