Hello,
the super infected plugin allows you to set different speeds for various special infected.
Example: 'l4d_super_movemultiple_hunter", "1.3", "movement multiple of super hunter [0.5-2.0]'
By setting the chance for a special infected to spawn to 100%, they should always move with the newly set speed.

The most recent version should still work. Unfortunately, not all super infected spawn with new colours.
