1136 and 1138 codes ONLY at full boost and throttle

My car has been throwing these two codes. I notice they ONLY appear when I floor it and typically in second gear going to third and it is full boost at say 22 lbs boost. Is this a vacuum leak? Doesn't throw me codes any other time.

What are the code descriptions? Too lazy to look them up.

lean codes.

My guess would be boost leak of the issue only happens in boost

Do you have vagcom or a way to check measured value blocks? If so check block 32. The first and 2nd % will be short and long term fuel trims bank 1 and the 3rd and 4th are short and long term bank 2. You should term should be +-5% your long term is +-10% if your + than you are adding fuel due to a vacuum leak, clogged fuel filter, bad fuel pump or could be bad Maf. It could be tuning if you are in the middle of tuning it but may not be if you havnt had any revisions lately.

I will look at the values and I do have a vagcom. I have had fuel pump replaced, new MAF, new wiring harness. I had a coolant leak that migrated up to the ECU and cleaned all connections with deox. I used to have rough idle and misfires, but that has seemed to go away with deox cleaning. So now it is either ECU damage or leak.
