Fully customizable from the look (multiple bezel colors), layout (set up a race, street or dyno gauge cluster) and mounting options (choose from 1,000s of standard vehicle mounts). Of course, all of the great COBB tuning is included - with enough space for 100 calibrations.

COBB PDK Transmission Tuning Optional upgrade for Porsche 991 Carrera 3.8L PDK Cars Only
PDK OFF THE SHELF MAPS
In releasing a product that has never before been offered, our Porsche Calibration experts created PDK calibrations that we felt would give the greatest performance impact as well as appeal to most enthusiast owners.  While the specifics of the map for each vehicle may differ slightly, below is a general representation of what to expect when using one of three provided PDK OTS maps.
All supported vehicles will have the following maps to choose from:
COBB Sport Map
A nice mix between the factory Normal and Sport Drive Modes.
COBB Aggressive Map
More ideal for vehicles being used on track or during competition.
OEM+
Cayman R PDK Calibration.  This can be used on the 987.2 Cayman S / Boxster S and Boxster Spyder to simulate the OEM Cayman R PDK calibration.
Below we highlight features that are integrated into the PDK Off The Shelf Maps.  For a complete list of changes made to the PDK OTS Maps please see the
PDK Map Notes Page
.
Increased Auto Shift Points
This feature increases the highest RPM at which the PDK will shift to the next gear in Normal, Sport, and Sport Plus drive modes.
COBB Sport does not increase the auto shift limit.
COBB Aggressive and COBB High Torque Aggressive increase the auto shift limit to a maximum of 7900RPM
Race Start Lite:
This adds Race Start to Porsche Normal and Sport drive modes for all cars (
including
vehicles that do not have Sport Chrono). In COBB Sport, COBB Aggressive, and COBB High Torque Aggressive maps Race Start Lite is set at 5500RPM in Normal and Sport drive modes. Race Start in Sport Plus remains at the factory 6500RPM
Increased Shift Firmness
COBB Sport, COBB Aggressive, and COBB High Torque Aggressive maps raise the shift firmness to help reduce clutch slip.
Increased Clutch Pressure
COBB High Torque Aggressive maps raise the maximum clutch pressures to help reduce clutch slip after shifting. The COBB High Torque Aggressive map is typically used on vehicles that have an increased engine torque output of 50% or more over stock. If the COBB High Torque Aggressive map is flashed to the TCU a PDK Relearn must be completed when changing maps back to COBB Sport, COBB Aggressive, Simulated Stock, or when uninstalling. Failure to do so may result in less than desirable shifting and/or TCU errors. PDK Relearn instructions are located below.
Minimized Continuous Clutch Slip
COBB Sport, COBB Aggressive, and COBB High Torque Aggressive maps decrease the RPM at which the clutch is engaged in continuous slip, generally between 1000-2500RPM.
Summary
COBB Sport: Increased minimum shift points, Race Start Lite enabled, shift firmness increased, and continuous slip decreased.
COBB Aggressive: All COBB Sport features plus increased maximum shift points.
COBB High Torque Aggressive: All COBB Sport and COBB Aggressive features plus increased clutch pressures.
