what is the benefit of aftermarket cams ??

[Faisalicious]

hello everyone,
i have a bulit D16Z6 turbo but a stock head and cam, i was thinking about buying an aftermarket cam. My question is how much power it will add and is there any other benefits that come with getting an aftermarket cam ?
thanks a bunch

how much power it adds is based off of the cam profile and the tuning after installing.
