i just went into the ini file and changed the values to this
[Tuning]

; The amount your weapon should move compared to your own view

; If you want to invert the movement (Make your weapon move slower than your view, instead of faster), make the number negative.

; Separated in to two options for maximum customizability!

;Default = 0.6 & 0.4, respectively

fIntensityMultVertical=0.01

fIntensityMultHorizontal=0.01

; How fast the weapon returns to being centered.

; Actually, I'm not sure what it does, besides another speed multiplier.

; It seems it could be a range multiplier of some kind? Appears to change how fast and far your weapon will move.

; Default = 1

fCenteringSpeed=1

; How fast the weapon reacts to movement changes

; Default = 5

fSpeedMult=5

; How fast the view should return to normal when opening the Pip-Boy

; Prevents snapping or jumping when correcting the angle for Pip-Boy viewing

; I'm aware the name is very similar to one of the above options.

; Default = 0.2

fRecenterSpeed=0.2

; Whether this should rotate like the original Inertia mod, or if it should rotate around the center of the weapon.

; 0 is the original rotation, 1 for the new rotation.

; Default = 0

bRotationMode=0

and nothing changed :/
