I would like to see more fuel on a boosted application. .82-.83 Lambda is what I command my car N/A! that is lean on these cars. It looks as if you were running out of injector, the pump duty cycle was not maxed out so that looked fine. The beginning of the pull the car was at .79-.80 which is what it needs to be boosted and then it drops to .83-.85 towards the end, fuel was dropping the whole pull. Also if you look at the pull the car was pulling timing throughout the whole pass on the knock sensor, it wasn't much at just 1* if you would have pulled .50 to 1* globally it would have not shown knock on the log.
