The higher the headspeed I get more tail wag

What do I adjust to compensate for tail wag when the helicopter is moving forwards fast.
I want to adjust for low, medium and high head-speeds in each bank.
So what is the equivalent of adjusting PIDs for the tail?
Note:- Tail is smooth and has new components and the wag is very small at low head speeds.

Tail Gain should be reduced with higher RPM.
Make sure to set Pirouette consistency parameter correctly too. What is your current value?

Pirouette Consistency = 165 (note:- number 5 only shows half of the number 5 on my iPhone.)
Rudder Feed forward is 6
Rudder REvomix is 1
Rudder Stop Smoothing is 5
Rudder Stop Gain CW is 120
Rudder Stop Gain CCW is 80
3D master mode is not Enabled.
Helicopter is a standard build OMP M4 Max.

Hello,
with OMP M4 there are reports when mechanics is very stiff from factory. It require certain tweaks, making it butter smooth.
What could help is also moving tail servo arm shorter (ball linkage closer the servo). Then readjust rudder end points. This will allow to increase Gyro Gain and get better tail performance.
