Am I referring to P-factor?
I don't know what you're referring to but I'm sure you're noticing something and there is an explanation for whatever it is.
P-factor only causes yaw when the propeller disk is not perpendicular to the relative wind. For example if you were flying level with a nose high attitude you would have additional yaw from P-factor but it's not likely you would notice it because of the yaw already caused by the helical slipstream.
