Currently it has an SSS that uses an oilhearts afterburner, but there's 2 problems with it.
1.The speed boost is very minor(25% on slow ship)
2.It disables turning, which makes it die more often as it uses it at random times when on low health, including when it's moving towards a wormhole and facing at the enemy.

So the suggestion is
1.Flat speed bonus instead of a percentage(maybe 20 speed?)
2.Some different afterburner, that doesn't stop turning completely.
