my customer ran into this problem with his stock ROM 52680020, I even tried a 52680017 and the problem would not go away. Again this problem began after a boost leak test BEFORE the ecu was flashed.

I had a bone stock 2008 GSR, the kid just put a MBC in it right before the tune.

I don't think it has anything to do with the tune/ROM, it's a mechanical issue, I just don't know the fix. My customer went to the dealership eventually and they tried to convince him that I put an IX tune on his X because "that error code is for the IX and not possible on the X". I tried to explain to him that obviously I didn't put an IX tune on an X and furthermore the issue was there before the tune anyway.

Has anybody had any luck with these codes?
I just had these pop up on a 52680015. CEL was on before the flash, but I didn't check the codes. I cleared the codes and they popped right back on. I'll tune the car with the codes stored and see how it goes.
