Both are true. Most people with tuners (like myself) are constantly adjusting because when you start pushing, you've got to keep on top of your climate for the best performance. BUT, that being said, you can find a happy medium, get good performance and not teeter on popping something too.

That being said, there's really only so far you can reasonably go with a pushrod engine, and sometimes you can't beat displacement. Even then, those have limitations.

I'm sure there's a reason why we only see a handful of local V6 guys pushing into the 10's, but you see V8 cars like that all day long at the track.
