Read Marcin's posts on tuning. But be prepared for information overload!

Cylinder charge is what it is, goes straight to the peak
pre-firing cylinder pressure hence timing needed (burn
time decreases w/ charge pressure & temp etc.); also
(with timing) goes straight to torque. More is better.
It is a computed product of the MAF and speed density
airflow inputs so can be messed around by any tune
errors there. If you are making mods that improve the
cylinder filling / scavenging expect CylAir to increase
(at the top end anyway).
