Got 30FF, 30FE and 3100 on a trackday a couple of weeks ago (can't replicate on the road because afaik it takes a while of overboost/underboost to trigger half CEL). Was around 30-40kph down on top speed on the straights so definitely wasn't pulling as it should have.
This is a random 3rd gear pull where i caught some strange wastegate duty dip and throttle closures, they look like overboost?

Have a feeling wastegates are slowly due for replacement, but will replace boost solenoids and maybe rest of the vacuum lines first (already have some 4mm samco ones because it's a bit hard to get 3.5mm ones it seems).
also a 3rd and 4th gear run with no WG duty dip but also throttle closures (i felt them also on track and i guess on the road too, like i wasn't holding as much throttle as i am), DTC fully off in both logs:

Doesn't seem to be any major timing corrections.
And a last years run with no throttle closures:

The only difference now is i have a FMIC but still same stage 1 map, not the + one. Kinda afraid something would break on the 1+ map but maybe should try it if it boosts higher and maybe wouldn't overboost then, but it's probably not the FMIC causing it... Everything else is the same as last year.
Any ideas?
