Yes, exhaust blockage would certainly be a cause.
Checked exhaust and there's no issues... I'm actually out of things to do, it almost feels as if it's being restricted because believe it or not, it's actually very hard to get it into high RPM's, it feels really sluggish and feels like I'm hurting the engine when I push past 5k... Anything that may cause that?

Are you sure the misfires/cuts your feeling aren't just throttle closures? Everytime my car would overshoot boost target it would cut and it feels and sounds like a misfire.

Nah it's definitely not that, it feels pretty lack luster every day and everytime it starts up on a cold start, it misfires like a dog for 2 minutes until the car idles to it's normal idle RPM.
But I may of found the issue, I'm getting Exhaust vanos errors now with a 3100 code after doing my valve cover gasket and repairing a vacuum leak. Wonder if it's triggered my issue

Yeah you may be on the money, look at my recent reply to slowestN54 on this thread, I've got a picture of my codes and it looks to be VANOS issue. But don't know why it got triggered after doing my valve cover gasket
