Torque and P-Factor settings for the V35B

Hey,yesterday I flew into KHQM with this bird, on RNAV approach for runway 6. As I have the RealityXP GNS 530 installed, I flew it as a fully coupled WAAS approach. It took me right along the GS perfectly to the runway.Now, there was a very slight crosswind, 054 at 5 knots, so that's almost a headwind. The AP flew me straight-on towards the runway, without any need for crosswind correction.Obviously, a few hundred feet from the ground, I disengaged the AP to anticipate the flare and put the baby down. But the plane then then really had a, to my opinion, overexaggerated tendency to bank and yaw left. I ended up landing almost into the grass, even after trying to correct with right aileron and rudder.Couldn't be the wind, obviously, cause even if that would have had any effect, it should have pushed me to the right I reckon.So my guess is that it's my torque and/or p-factor realism settings. I have them to full max, but I've read a few reports that FSX overexaggerates these parameters.So my question: what are your settings for best realism, for this wonderful plane in particular, and for single engine props in general ?Thanks a ton for any reply.MathieuPs: I'm not a real world pilot, just a flightsim enthusiast.
