The APR TCU Upgrade enhances the operation of the DSG transmission in all aspects. The short-shift and 7th gear seeking behavior is eliminated, instead, shift points are optimized for maximum acceleration. Under part-throttle daily-driving in both Drive and Sport mode, the transmission remains calm and smooth. In addition the RPM limit is raised to 7,200 RPM to unlock additional HP, even on cars with just a stage 1 tune this can give a 20-20 HP benefit.
Finally, a user definable launch control system is enabled which allows a 3 step launch RPM based on pedal position. In addition the launch control limit is raised from 200 times to 3,000 times.

• 7,200 max shift point with gear dependent overshoot protection.
