it needs to be driven a bit before the Turbo can fully utilize the plenum to it's full potential.


People keep writing this doubtlessly because that is what their "tuner" is telling them....

Surely the way modern electronics work one or maximum two full bore runs in a loaded gear like 3rd will ensure that the ECU will switch to its "best" map with maximum fuelling, timing etc to allow for the greater airflow which the plenum is (alledgedly) giving - how can this take any more time than one full load run ?

The ECU will always "push" toward knock everytime full throttle is given, this is the way it works and it only backs off to a more conservative map when approach of knock is sensed..... "The backing off" or "giving the best map" happens in micro seconds - this is the whole benefit of modern Bosch systems.....
