Turbo Surging at Idle with Exhaust Brake

[RamIt]

Unfortunately when I first straight piped it, it never did it.

Ran it all summer and now that the temps are coming back down and the exhaust brake it kicking on at warm up I noticed it doing it.

So the issue definitely started happening post tune.

Whatever it is, hopefully someday someone figures out what is causing it and sheds some light.

I’d love my truck back to normal!

Every one of these trucks do this at some point in time. Mechanically you have zero issues. Does it make an annoying noise? Absolutely. But that's about it.

My unproven theory is that the actuator moves the VGT out of range post-tuning; causing the system to attempt to move the nozzle back into range.

The only way to prove that would be a running data log from stock until the problem occurs.

I have a 2013 I have owned since new.

Tuned/studded/dual disc at 15k almost 80k now and it has just started doing this.

It sounds terrible and my butt dyno says it runs better some days than others so I'm thinking my actuator is acting up.
