Welcome to you and your cool toy
I see you already have TuneECU and cable, so I'm guessing you have removed the restrictions from the first 3 gears, and opened the secondaries.
Plus you have Ramair so she can breathe. The next stopping point for power is the stock exhaust header. Looks good, controls heat ok, but restricts airflow. A good flowing header like CES, or Reband would give her more power down low where that mud monster needs it.
Keep us updated.
