    • COBB Aggressive and COBB High Torque Aggressive maps increase the auto shift limit to a maximum of 7400RPM.
  • 991 Turbo S
    • COBB Sport does not increase the auto shift limit on the Turbo S.
    • COBB Aggressive and COBB High Torque Aggressive maps increase the auto shift limit to a maximum of 7400RPM.

• 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 4500RPM in Normal and Sport drive modes. Race Start in Sport Plus remains at the factory 5500RPM.
• 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.
