Deadzone = 2
Saturation X = 98
Saturation Y = 98
Curvature = 30
I do this for both axis and it helps immensely.
Now the reality is that the Harrier is a real bugger to tank vs a Hornet simply because of the probe location. You need to get the HUD indications aligned with the prop edge and the probe line coming in between the HUD and the box that says "Left, Ready, Right" on it. Tricky, but its a practice thing. Lots and lots of practice.
