M113K TCU Tune
The factory transmission calibration on M113K-equipped AMGs is designed for comfort and longevity, resulting in slow shifts, excessive torque reduction, and noticeable slip — especially once engine power is increased.
The DTK M113K TCU Tune completely transforms the way the car drives, allowing the transmission to fully support increased torque while delivering faster, firmer, and more consistent shifts in all conditions.

What the TCU Tune Does
Our transmission calibration reworks shift strategy and torque control to unlock the true performance potential of the AMG SPEEDSHIFT transmission:
•Faster and firmer gear changes
•Eliminated shift slip
•Recalibrated torque limiters
•Improved throttle-to-gear response
•Optimized shift behavior in all drive modes
•More responsive manual mode
The transmission becomes sharper, more direct, and far better suited for performance driving.

Performance Benefits
•Stronger and more consistent acceleration
•Improved roll-race and drag-race performance
•Better control under full throttle
•Proven up to 0.2 second reduction in quarter-mile times
On the M113K platform, the TCU tune is widely considered the best bang-for-buck modification.

Driving Experience
Despite the aggressive performance improvements, daily drivability remains excellent:
•Smooth operation during normal cruising
•No harsh or erratic behavior in traffic
•Instant response in manual mode
•OEM-level refinement retained
The car finally shifts the way a supercharged AMG should have from the factory.
