Monitor
A healthy-looking pull overall: lambda stays around 0.85–0.89 at full load, timing corrections are small and the engine pulls cleanly to 6,800 rpm. The one thing to keep an eye on is boost falling about 0.2–0.3 bar short of target above roughly 5,700 rpm while wastegate duty is already near 90%. Together that points to the turbo running out of breath at the top end rather than a fault, but a boost leak is worth ruling out.
Boost shortfall in both gears, same rpm range
Both boost findings start between 5,700 and 6,200 rpm with wastegate duty near 90%. One cause explains both, so they shouldn't be read as two separate problems.
Log next time
Add Lambda target, so lambda can be compared with what the ECU asked for
Log one more pull in the same gear to confirm the boost pattern
Add a low-pressure fuel channel in bar or psi
Questions for you
Which turbo is fitted: stock or upgraded?
Was the boost shortfall there with the previous map as well?
What the data can't tell
Ambient pressure in this log reads 0, so boost is calculated with a standard 1.013 bar
One log can't show whether the timing corrections repeat

Findings
WarningConfidence: highTurbo system
Boost below target from 6,200 rpm
Between 6,200 rpm and 6,690 rpm in 4th gear, boost averages 0.30 bar under target, with WGDC going from 89% to 92%.
AI
In 4th gear boost averages 0.30 bar under target from 6,200 rpm, and wastegate duty is already 89–92%. The wastegate is almost closed, so the ECU has little left to give: the turbo can't reach the requested pressure at that airflow.
most likelyTurbo near its flow limit at high rpm– The shortfall starts late, grows with rpm and comes with the wastegate nearly closed.
possibleBoost leak in the charge pipes or intercooler– A leak gives the same picture; it usually also shows earlier in the rev range under load.
less likelyWastegate not sealing fully– Spool and mid-range boost track the target well, which argues against a wastegate problem.
What to check
Pressure-test the charge system
Compare with a pull in the same gear on a cooler day
Check the turbo's inlet and outlet couplers for oil or looseness

Insufficient dataConfidence: highFuel system
Some fuel targets were not logged
Lambda target is missing. Fuel values can be shown but not compared with what the ECU asked for.
What to check
Add Lambda target to your logging list for the next log.
