Your temps are pretty mild and this problem could only get worse with colder temps. Some options:

1. You can do a pull with the fuel economy +SF map. This will disable boost control and tell you if you can mitigate the overboost somewhat at 0% WGDC. Do a few pulls to high RPM (if you can do so safely) and we will get a better idea. If it does help quite a bit, then it means that some tweaks to the tune could mitigate the overboost somewhat at least at the current temps you are seeing.

2. If #1 doesn't help, then you must do something on the mechanical end. Examples would include: 1. put a catted downpipe on car 2. port wastegate + custom tune 3. external wastgate + custom tune. #1 is not guarantee that you won't still see boost creep but the chance are significantly reduced.

I had understood that the fuel economy map was not meant for spirited driving will that mess anything up? I also took another log today since it is 61 degrees outside and figured i would see some creep so here it is running same map as before:
