I read a lot of posts and something I see quite often is "get a custom cam" does this apply to most situations or just the higher end motors? Do they work with the factory computer better, or what is the main advantages besides having some one with expertise pick your cam.

Just trying to learn, I am staying quite mild with this engine (thinking stock cam with 1.7s) so again just trying to learn.
