i actually think this isn't correct:
"Felicity Farseer
...
Thrusters:
Dirty Drive Tuning (optimal mass multiplier) - max rank 3
Drive Strengthening (increase integrity, reduce thermal load) - max rank 3
Clean Drive Tuning (optimal mass multiplier, reduce thermal load) - max rank 3"
the drive tuning gives you an "optimal" multiplier, while it REDUCES optimal MASS of the thrusters.
