Waste gate rattle only when car is warm

My car never rattles on cold start or when accelerations/decelerating. The only time I hear it is when it does a warm start and I tap the gas to 2k.
Would tightening the rear waste gate fix this? I tried jb4 fix but I heard that's only if it it rattles all the time.

I recently took out my Vargas turbos and put back stock but never adjusted the wastegates.

I'd try fiddling with Menu 10/12 a bit. JB4 wastegate control isn't great for rattle. See also, if I take mine out, the rattle goes away. Adjusting the actuator won't fix it for long if they are actually rattling due to wear.

Oh okay I'll try that, just hard since they go away once the car is warmed up. Turbos only have about 40-50k KM. It only happens for about a minute or so but I'm just a bit OCD lol

When you say take yours out do you mean the jb4?

No codes and I recently replaced all my vacuum lines. When I max/min out menu 10 nothing happens, still rattles. I can live with it but it's annoying for the ~1-2 minutes warm start.

I know it's been a long time but did you by chance figure it out?
