I have a Kremer motor that does that at around 2500. It over boosts ( 1.3 ) till around 4K then settles in to 1.1 after. The spec sheet says 956 waste gate which is in perfect condition, so I suppose this is right. It definitely gets more mid range power this way. I would be concerned if it stayed @ 1.3 bar into the 5 to 7K RPM range. Plenty safe AFR at lower RPM and stays good to red line. The broader power range is good especially with the 4spd and you get caught out below the torque peak. It also helps lessen the boost punch you get with a stock 930 as the power builds sooner and is more linear( and controllable).
