Full Answer
Boost by gear is a documented custom feature for the FA24DIT, and multi-map capability is listed among the platform's custom feature set.
**Boost by gear** lets you set different boost targets per gear rather than running one target everywhere. Per-gear boost control alters both boost targets and wastegate duty cycle, which allows several genuinely useful things: equalising boost across gears so the car feels consistent, reducing boost in low gears where the car is traction limited, and reducing boost in high gears at low rpm where the drivetrain is most loaded.
That last use is the one worth dwelling on for a VB. The platform's binding limit is torque through the transmission, and torque is worst where a low gear multiplies it. Being able to pull boost out of a specific gear is a genuine reliability tool rather than only a performance one - it lets you protect the gearbox in the situation that stresses it most, without giving up power everywhere else.
Two documented caveats. The feature's peak values reach 20 psi and the factory boost table should be reset for proper blending, so it is not a set-and-forget toggle. And boost by gear cannot be used alongside altitude boost rescaling, because the two perform overlapping functions - you choose one.
**Multi-map capability** is listed among the first-party custom features. In practice a multi-map setup means holding more than one map on the car and switching between them, which is how owners typically run a pump gas map and an ethanol map on the same vehicle without reflashing between fills.
Both require ATLAS 2026.1 or later, so confirm your version before planning around them.
The broader point: these are things a conventional handheld map flash cannot add, because they are new logic rather than different numbers in existing tables. That is the specific gap ATLAS's custom feature library fills.
