The boost retard system activates a different amount of retard for each gear.

Explanation:
Ignition timing retard from boost is controlled by boost pressure and engine speed, not by which gear you’re in. The engine control unit uses inputs like manifold pressure and RPM to determine how much spark to retard, aiming to prevent knock and manage power as boost rises. The gear selected doesn’t directly alter that retard amount in a standard boost-retard setup, so the same retard value applies for a given boost level and RPM regardless of gear. Some nonstandard or customized setups could map timing differently by gear, but that isn’t the usual behavior.
