It's completely max'd out, and is almost impossible to survive.
Oh, and cruise, afterburner, etc speeds have been changed to help distinguish the various ship's abilities.

The Fighters scoot...
And the Freighters have more speed than their FL counterparts.
(There are several ships that can approach Tradelane speeds when mod'd right.)
(Try the Stiletto, Morningstar, or Gladius with 3 Super Afterburners!)
Watch your 6!
