for the interdiction-minigameplay:
- there is not really something you can do. your sc-manouverability is fixed by ship-type, not by outfit. some people claim 4 pips to engines make it better during interdictions, which is to doubt.
after submitting an interdiction or loosing the mini-game:
- a shield that buys you time, till fsd-cooldown is over and you can reengage. a 3A on a t6 should be enough.
- chaff, so interdicting pilots can't use their gimbals and turretts.
- a good power-distributor and good thrusters. a good distributor allows you to boost more often, good thrusters make you fast.
... boost, boost, and fly away. if masslocked, highwake to another system.
