Does anyone have logs from when their wastegate(s) were dying?

This question will be answered once my vargas turbos go in, but I'd just like to see some examples in the mean time to help me figure out if what I'm experiencing is in fact wastegate related or a boost leak. I've had a boost leak before and this feels very different.

Mine have started rattling recently. PROcede is giving me issues as usual so I'm going back and forth between it and Cobb. What kind of log do you want and with which tune?

I'm having no issues with the procede, this issue i'm having has just been a longer-term decrease in responsiveness of the turbos. As the rattle increased, there was more and more lag. Now it feels like a single turbo. I'm getting new turbos anyways, I'm mainly just curious. I'm only really looking for logs from people who's turbos are significantly different feeling from when they were new.

Did your PID DC% go through the roof?

Mine never go about 60% and I was wondering if that was the norm or high?

I'm interested in this too to troubleshoot a no-booost issue!

No boost should be pretty easy as it should be a significant leak. Old wastegates wouldn't give you a no boost scenario.

They're higher than normal, but not totally maxed out like when I had a bad boost leak. Cold weather plays a roll, but they're still higher than they should be, and of course the log is just funny looking with boost ramping up slowly
