Depends on what you mean. One man's "works fine" is another mans "what a POS to drive, I have to use two feet and it stalls when cold and bogs in the winter" and so on.
GM didn't put all the other stuff on because someone dared them to lose money!
When I say "it drives fine", I really mean "Your mom, who drives a Camry, cold-started my truck in the winter and drove it and thought it ran really well".
Switching to an aftermarket intake usually means losing the heat crossover (though not always) which makes them ugly in the cold. Same with an open filter element and no heat stove, it's bog city.
Removing smog equipment usually just screws up the carb calibration without improving performance, so I never do that. I mean if my truck originally had an A.I.R. pump I wouldn't seek one out just to have it, but I sure wouldn't take one off to save 3 horsepower unless I was in Pro Stock. And the PCV is an important anti-wear device, so I wouldn't remove that. And that's about the entire extent of smog equipment on these.
