Good to hear it working well for you. Since you brought up BF4 I thought this is a good chance to share a vehicle tip.
For optimal vehicle performance create a new setting and set an activation key and toggle behavior. Then use a boost of around 3850 for PS4, 3980 for X1.
I'm using this curve

and this is what my vehicle setting actually looks like:

The passenger seat in those vehicles uses the soldier hip deadzone so you may want a second setting for that if the above settings bother you.
You can also set the right stick to keyboard keys in addition to your mouse for faster turning via your keyboard. This is under the keyboard drop down's advanced menu.
