The type of air you run makes a difference, too.
Helium, the smallest stable molecule, moves through your system faster, so for the same amount of pressure you will lift and drop much faster than standard air or nitrogen.
Hydrogen is even smaller and faster, but unfortunately is highly flammable, and extremely expensive to boot, so it's not a good idea unless you want to destroy your truck in a spectacular fashion!
Larger valves and lines only work to a point, also. Slam bags only have a 1/2" port (or dual 1/2" ports if you go with HE or XS series bags), so at some point you won't benefit from larger lines or higher flowing valves.
