When a player reveals a red maneuver for a stressed ship, he has an opportunity to resolve card effects that change the maneuver’s difficulty or change the maneuver to a different one (Adrenaline Rush, Navigator, etc.).

From the FAQ on Red maneuvers

When a player reveals a red maneuver for a stressed ship, he has an opportunity to resolve card effects that change the maneuver’s difficulty or change the maneuver to a different one (Adrenaline Rush, Navigator, etc.). After resolving these effects, if the ship would still be executing a red maneuver, the owner moves the ship as if it were assigned a white [ 2] maneuver instead. The speed, bearing, and difficulty of this maneuver cannot be changed.

From the same place on Saboteur:

If Saboteur flips a Damage card that causes the targeted ship to be unable to resolve a maneuver (such as Thrust Control Fire before a ship attempts a red maneuver, or Damaged Engine on a stressed ship before the ship attempts a turn), the player controlling the ship with Saboteur equipped gets to choose the stressed ship’s maneuver when it activates during the Activation phase.

Does Saboteur (a card) override the general rule?

At present, yes, but I suspect that's an oversight. Probably worth giving a poke on the rules questions form to make sure the relevant people get notified.

tsi is correct, as usual, but poor Saboteur needs all the help it can get.

All cards override general rules, that's what they do. The specific rule always supersedes the general rule. Here, as TSI puts it, it's probably just an oversight that will be fixed the next FAQ

The Saboteur FAQ entry doesn't really even apply to the current rules on how to handle revealing a red maneuver when stressed. It needs to be updated to remove confusion.

FAQ entries for cards are not themselves rules.They can be used as precedents to determine how rules should be interpretted but when they are not supported by any rules, they should no longer be valid.

The Saboteur card text does not grant some special exception to the rule about handling stressed ships being assigned a red maneuver so this isn't really a case of card text overriding the rules.
