If not, you can buy pressure test kit for relatively cheap.

O-ring on the charge pipe?
Iíd recommend another log first. Initially this car was building zero boost...itíd be useful to see if itís making boost before doing more diagnostic.

I'll be doing another smoke test again. I'm also waiting on a new chargepipe to come in. I heard damaged cats could also cause 30ff but I don't have any other codes.

Hey so just a heads up, this is exactly what my car was doing when I had my 30FF. My initial experience was pretty similar to yours. I had a loose charge pipe to IC connection at first which i fixed but the 30FF remained

The smoke test then revealed the blown solenoid to rear turbo vac hose that was my main culprit. I had a louder exhaust note during this time that was a result of the wastegates being stuck open since there was no vacuum to close them.

That second smoke test you're planning will def help even if just to eliminate a possibility

New log. Wot until limp mode pops up. Wastegates rattle loud on start up for 30 seconds. Can also be heard while deceleration.

Yeah youíve still got a major issue. Youíre not building any boost. Are you sure you donít have a vacuum leak?

Then the clamoring you are hearing is coming from the front turbo.

There is a DIY about how to tighten the wastegate on the front turbo.

I got an xi so I know it's gonna be much harder. I'm still going to perform another smoke test and install my bms charge pipe thankfully. Might check my o2 sensors as well. If nothing changes, I might as well buy new turbos with upgraded wastegates...

Youíre probably better off moving this discussion to the n54 forum. There itís more likely to be seen by others with experience.

Based on your log youíre not building any boost. I would think even if youíd wastegates were shot youíd still build some boost. Iíd figure out why youíre not building any boost before I put in new turbos...

I think you need to :

1) go over ever connection in the intake system
2) check every gasket
3) do a pressure test
4) do another smoke test
5) do a pressure test with a mityvac on the wastegates themselves
6) try using the washer method to tighten up the wastegate on the front turbo actuator
7) check to see that the vacuum solenoids are working correctly
8) check the connections on the outlets/ perhaps update the gaskets
9) check to see if your vacuum canisters are holding air tight

10) double check the throttle body connection to the intake manifold (gasket), the intake manifold gaskets themselves & charge pipe gasket between the charge pipe & the throttle body.

11) make sure your OEM blow off valves are working correctly.

RB makes several variety of turbos. His RB 1, RB 2's are extremely cost effective for what you are getting. The RB 2's and beyond will require an upgraded LPFP. If you pay him by cashier's check, he will give you a $300.00 discount. The failure rate of his turbos is extremely impressive. Almost none...

I'm gonna try one more time. I tested the canisters and solinoids ( brand new Pierburg), both seem ok. The canisters release air when I take the vacuum lines off. I'm patiently waiting on my new bms chargepipe to see if anything changes.
