707 PS (+95 PS) on production hardware with vehicle-specific Lambda‑GT calibration
The GT 63 PRO is the sharpest model in the range: cooling, aerodynamics and chassis are designed for sustained load from the factory. That is exactly what the calibration targets – power that is available in the same form on the third or fourth fast lap. Lambda‑GT presents further stages under Performance packages.
Boost pressure, cylinder charge and ignition timing are calibrated so that the gain is available across a broad rev range and the reserve the factory built in for sustained load is preserved. The aim: even torque delivery and predictable behaviour on corner exit.
The GT 63 PRO differs from the GT 63 in standard output, cooling package, aerodynamics and software version. Lambda‑GT reads out the data version of the engine control unit (Bosch MG1CP003) in the specific vehicle and calibrates on that basis, instead of transferring an application from another model.
In a track-oriented car, component protection and temperature monitoring are part of the performance, not its opponent. The additional power is calibrated so that it remains available within the intended operating limits.
Changes are developed against defined targets for performance, driveability and thermal behaviour, verified by measurement and documented. The GT 63 PRO adds one more target: power must remain stable over an extended full-load phase.
The test checks whether boost pressure, temperatures and torque delivery stay within the intended range – the way the GT 63 PRO is used on track.
The customer receives the certificate for their vehicle. With a model built in small numbers, no value carried over from experience replaces this individual measurement.
The calibration can also be extended with further functions or performance components – such as adjustments to start-up and idle behaviour, defined sound functions or additional performance parts, integrated into the overall calibration. Examples can be found under Real vehicle projects and Personalised vehicle configurations.
