In older versions of the engine, before 4.11, there was a bug with PSVR that wasn’t accounting for the pantoscopic tilt, which could make people feel uncomfortable. However, since that’s fixed, the movement should be one-to-one.
Can you describe the problems that you’re having with the tracking? Sensitivity isn’t a configuration option, since in general, you want to have the tracking be exactly one-to-one with the motion of the headset.
