I have added boost to my setup which seems to be making things better
Here are my thoughts on boost, I'll copy/paste from another thread.
Boost can be useful for some low Turn cap games or games that utilize timed acceleration. IMO though, it's best purpose is for trying to make a dead zone work with an unsupported game or for Vehicles, which are also unsupported. Boost can also help with AA, but it's a slippery slope.
The real difference between Boost and Ballistics is Boost is instantaneous from point A to point B. It allows you to manipulate the starting point of the right stick. So if you pick up your controller and slowly move the right stick you will feel a certain amount of play "Dead Zone" before your movement actually registers on the screen. As you push harder on the right stick your movement speed will increase. Boost allows you to completely bypass that dead zone (if you wish) and you can pretty much choose the starting point of your right stick movement. So if you crank Boost WAY up, it's just like starting your movement at the point where the right stick is immediately pegged. Ballistics allow you the same benefit except you can slowly ramp up or down to the desired speed instead of getting there instantaneously. Also Boost only works as acceleration, where ballistics can also slow your movement down if so desired.
Think of it like an electric and a combustion motor.
- Electric power is instantaneous, as soon as you punch the gas you have the max output that your motor can draw from it's power core. - BOOST -
- Combustion motors have alot of mechanical parts that take longer to build up torque. - Ballistic curve -

Now ballistics can be instantaneous obviously, if you make a ballistic like the electric graph above.
I hope this helps you understand when and why you would want to use one or the other or maybe even both sometimes.
