I have no codes - anywhere...my car is clear of DTCs again - w00t.

However, the above graph shows the problem.

Throttle % is fine because requested boost looks fine, however actual boost is not as you can see?

Does that resemble a boost leak? Seeing as actual boost rises with RPMs even when requested boost tapers down?

TIA!

I will be doing more logging later this week to check other blocks.

Looks like a possible boost leak. Best run a pressure test.
