That's what I'm talking about after the ecu reset. Given enough time for the ecu to relearn the engine, that dip will flatten out more like it was in the first pull. The boost had nothing to do with the torque dip. Must be timing related combined with the rich A/F. Both pulls are with the ROM tune. Never got the stock ecu on the dyno.
