EXACTLY. That’s why I always ask what someone’s definition of “…” whatever is so you can see what they want, what they can live with, what they can tolerate and what they can’t live with.
Back in the day, it wasn’t usual to have an engine idle speed of 1400 RPM. It never bothered me (it would drive me bat crap crazy today though because cams have gotten so much better, plus I’m a much better tuner than I was then) but some guys would literally lose it with that idle speed.
So I would do a bit of tuning, unplug the tach and make them drive it. Once they signed off on it, I’d hook the tach back up and the vast majority of them would go berserk. So you turn the idle down and let it struggle.
Thats one of those things you have to find out about people. And then verify it, because most guys think they can handle more then they really can.
