Here is a log showing quick (< 0.7s) shifts from 2nd to 3rd to 4th. Again, same map, only difference is shift speed: https://www.bootmod3.net/log?id=5e7a...0b43508e6fe39e


This time the delay between pedal at 100% and waste gate going above 80% is 1.1 seconds in both cases - longer than when I shifted slower. The duration between pedal going to 0% for the start of the shift and the waste gate going above 80% is 1.7 seconds

In this case, the waste gate never goes to 100% in either shift because boost is already rising fast enough at the point where the waste gate starts to behave normally again. There is a visible bump in the WGDC trace though, which shows that something is going on.

Finally, a log here that shows no waste gate bump at all - the effect is totally masked, because the shift was fast enough and the revs high enough that boost didn't drop enough for the wastage to need to be closed by the time it was operating normally again. You still see the bump on the 3rd to 4th shift, but not at all on the 2nd to 3rd: https://www.bootmod3.net/log?id=5e7a...0b43508e6fe3b4
