Everything is Very Simple

Watch my hands:

• 1) On any ship you dock with the shipyard of the faction with which you are most friendly for upgrading. 
• 2) Put the most expensive gun / equipment for all the money.

• 3) Fly to the shipyard of the faction with which you have a near-zero relationship, and again you dock for an upgrade.
• 4) Sell everything that you bought earlier. 

The point is that the friendly faction sells upgrades cheaper than neutral. And the cost of installing and returning the upgrade at the same shipyard is the same. Buy for less, return for more. Congratulations, you spoiled the impression of the game :)
