Deleted - strange exhaust noise @ idle

OK, so I have been deleted for about 3000 miles so far. I normally run in the stock setting, but sometimes in tow.
I noticed a week ago when I was idling, (I was hooking up my trailer) that my exhaust tone changed, and I got a whirl like the turbo was spooling up. Only lasted about 2 seconds.
Now it seems like every time I stop and idle a few minutes, that it does it all the time. I even was sitting at the bank drive thru and saw my boost go from 0 to 1 for a split second.

Is this normal?????
Is it ok to idle for longer periods since I am deleted? I never let it idle before, I always shut it down.

I have the egr block of plates sitting here on my work desk, but haven't had a chance to install them. I have my mini max set to H&S pyro.

Any help would be appreciated. Thanks

I can't answer about exteneded periods of idling, but mine does the same turbo spool as yours. Has for 11k miles. No issues. Sounds cool.

Usually it is common for the egr to cycle and cause this noise. Normal

Thinking about getting rid of the stock 6.7 turbo?
Check this out... and research before buying

îIf you watch your egts while it happens temp goes up 20-30 degrees then comes back down.

I notice with mine once idling egt temp is below 270-275 degrees the process stops.
After I've been driving and come to a stop. If my egts are above 300 degrees. It does the cycle several times.

I'm not sure but I'm wondering if it does the process to help cool egt temps as well.
