Why does no one do this?

A lot of my friends and I are looking for more ways to get more HP and they keep saying to have the CPU remapped which doesn't seem like a bad idea. How come I never hear about it here?

because a rock is a rock, a tree is a tree and the best way to beef a 4.0L is to stroke it to 4.7L

Because u can't get much out of a 4.0. Better off spending it elsewhere.
