Every Pirate Base tunes the engine of your ship to make it faster to accelerate and to increase its speed. This service gets progressively more expensive, the more often this is done. This can be done several times up to a maximum of 30 times. 

The first service costs 14.400.- credits.

Comment by Arnold:

The speed increase is enorm. While cruising at a speed of max. 190 km/h without engine tuning, this increases with 30 tunings to 790 km/h. A speed increase with 12-15 tunings is fast enough to hunt and outrun the fast Xenon M2 destroyers and gets you from A to B in relative comfort.

Comment by Melissa Banks:

As 30 engine tunings are very expensive, you have to make quite a bit of profit first, exactly 37.494.000 credits. The algorithm for the calculation of step A to step B of tuning is:
 

1200(b³-a³)+5400(b²-a²)+7800(b-a)

The following table shows prices of every tuning step.
