Well, I know that the numbers you've given are not concrete, they are good ideas for perks nontheless. Mine are:
 * Countermeasures Package
 * Smoke pops and flares/chaff fire out to deter lock-on and hid the vehicle


 * Autoloader Package
 * Quicker reload


 * Sensor
 * Auto spots enemies that are within view (a small circle with the crosshairs at the center, and proximity scan


 * Mechanic Package
 * Vehicle regen sped up and disables at lower threshold
