Boost issues
As it turned out after studying data logs the culprit was a bad dome pressure sensor. We discovered it on day 5 when on the first pass we hit a dome pressure safety which made the computer dump all CO2 and revert to wastegate.
Looking at dome pressure in the data logs, it was very unstable. Boost curve was all over the place causing spikes. In the picture the bad sensor is on the right and new sensor is on the left. Big difference. Another lesson learned. Don't use cheap sensors in critical components.
