Such as apexi PFC ?

 

I think its more ability to tune for bigger bhp with options for switchable maps anti lag and true launch control.

 

so would i gain bhp by puttin an apexi power fc in mine and getting it mapped again even though ive got a standard ecu mapped by jolly green monster ? or will i see little/no differnce

thanks a lot

Your standard ecu is many times better than most aftermarket units.

 

If your cars been remapped it should be running its best for what ever mods you have so i don't think you will make much of a gain if any. If you are planning on big mods and want the fc controller to tweak it might be worth looking into but you will really need to know what your tweaking or could end in disaster.
Hope this helps
