If you’re an owner of a Porsche 911 (991.2), O.CT Tuning make your ride faster with a few upgrades that lift the output of the Carrera, Carrera S and Carrera GTS considerably. By fiddling with the software of the engine control unit, the Austrian tuner has managed to obtain as much as 430 PS and 520 Nm of torque from the turbocharged 3.0-liter unit that powers the 911 Carrera.

That’s a 60 PS and 70 Nm of torque increase over the stock car. And if for whatever reason you desire more, then O.CT has the Stage 2 ready, which pump out max power to 475 PS and 580 Nm.


The Carrera S enjoys 475 PS and 580 Nm of torque, up from 420 PS and 500 Nm of torque, whereas the GTS brings 520 PS and 640 Nm of torque to the party, 70 PS and 90 Nm of torque more.

O.CT’s ECU remap was already available for other 911 (991) models. The 911 Turbo, for example, has 669 PS and 830 Nm of torque, or 880 Nm with overboost. The 911 Turbo S enjoys an identical output from Stage 2. The former normally has 540 PS and 660 Nm of torque, and the S is 40 PS and 40 Nm of torque more powerful from the factory.
