It is a rev limiter at the point in the datalog about (11:10) Disable launch control and the speed limiter see if that helps.

but boost cut on settings = 1600 mbar
on 2:35 maximum boost is 1592 mbar
Re: afr going to lean on boost
The datalog shows the MAP at a far lower sample rate than what the ECU sees. The datalogged MAP was 99.5% of the boost cut pressure, but there was one or more values at 1600 or higher pressure.
