None really benefit till you get the fuel controller hooked up. Actually I would not add anything else till you hook up the fuel controller.
With the slip/on, uni-filter, open air box or ehs lid, and fuel controller you should prolly see maybe a 5-6 hp increase.
What you will really notice it throttle response. Its noticable. Pulls way harder through the gears. And alot better topend.
You will have to have separate settings for your controller for each situation.
ie: (1.)Uni filter with airbox lid.
(2.)Uni filter with no lid or ehs lid.
I have a powercommander 5, so I am not sure on the settings for the fuel controller you have, Maybe someone else can add to this that has experience with one.
