One thing that disturbs me a bit is that most tuning problems are low speed related, and the low speed system is not tunable on a Holley. Then most people start changing main jets as this are the only jets to change. Yes, they do affect low speed, but only to a small degree. The biggest change occur around 3000 rpm or so. The idle screws take care of the idle, but as soon as the blade leaves the idle, the transfer slot takes over. With NO adjustments.
