Coming from the factory with 530hp in the Porsche turbo s, it was already at a new level of quickness. Having done r&d on a 2010 turbo pdk and our own 2011 turbo s pdk, we were familiar with and where the cars strengths and weaknesses were. Even though the turbo s comes from the factory with 30 more horsepower, there is always more room to improve. Not only looking to make strong power, we also improve the delivery and driveability of the 997 turbo s throughout the entire rpm range. With our very own 2011 Porsche turbo s we were able to experience this dramatic change in performance by the ecu flash. Typically when running the turbo in sport mode, the vehicles throttle response and low end torque is noticed on both the dyno and street, however based on egt temps, sport mode can usually yield lower mid to top end power. The ecu tune is effective in both standard and sport mode. Typically you will see the boost increase to 16psi in standard and 18-19psi in sport. With sport mode on, the car spooled up quicker making peak torque at about 400rpm faster. However this then tapered off earlier as usual with cars in sport mode. Overall, the substantial increase in performance still retains a comfortable daily driveability experience. The power is there when your foot wants it, but the Porsche never loses its 997 comfortable feeling.
