Tell me if anyone has ran across this problem. The other day I got into full boost and afterward noticed the exhaust sounded like it had a massive leak. Got it home and checked the downpipe gasket and while down there realized the exhaust was coming from my o2 dump. Next morning I went ahead and pulled the wastegate actuator off and checked the flapper. The rod it's connected to actually slides out a bit. Didn't think much of it at the time and sprayed everything with wd40 and called it a day. Fixed the issue and thought it was smooth sailing. Well yesterday I got the 3" turbo back installed and I wanted to see if there was a difference in power. This time while in boost it felt sluggish up top. and once again the o2 dump was screaming. So picked up a new exhaust housing from Geno and went to work last night. One thing that struck me odd though was the fact that the flapper arm is sliding outward away from the housing. Both exhaust housings I got from Geno are solid in that direction and only flip up or down.
Here's a video of what I mean.

In the vid you can see how the flapper goes off center of the hole and is very hard to flip side to side
