by the look of the log parameters you using oft so assume its and sbd turbo kit.
They have had problems with the early BOV , not sure if your running one.
Also log the injector opening times for port and direct, it might be tripping the overboost fuel cut (you might have dodgy MAP sensor) fuel cut so see if the injectors shut off when it falls on its face.

looks weird in that section of log the maf (air flow remains fairly constant yet boost drops, looks like it could be venting/leaking somewhere. but could be the overboost fuel cut.
