APR DSG DQ250 (6-speed) upgrade

Optimised shifting, higher clutch pressure for better power transfer, faster shifts and revised thermal management.

An upgrade to the gearbox control unit software that takes its operation to a higher and more logical level.

The upgrade brings faster shifts, optimised shift points based on engine load and better power delivery under acceleration. It also increases clutch clamping pressure and adjusts torque management so that the gearbox copes better with higher engine output.

There is also a big difference in Sport and Manual modes: the gearbox responds faster to the paddles, at full throttle it shifts at more suitable revs and the delay between the driver's command and the actual shift is much shorter. The upgrade also lets you customise, for example, the Launch Control revs or the automatic upshift behaviour in manual mode.

The result is a sharper, more immediate response in spirited driving, while in everyday driving shifts remain smooth and comfortable, without the annoying low-rev lugging.
