Porsche 997.2 Carrera ECU Tuned Adding 21 Wheel Horsepower VRTuned.com July 30, 2010 Company News Vivid Racing just had the pleasure of working on this 2009 Porsche 997.2 Carrera PDK car. The new 2009 and up Carrera is DFI (Direct Fuel Injection) and is available in the PDK (paddle transmission) or 6speed gearbox. It is also available in the 3.6L or 3.8L version. The particular PDK, 3.6L, Cabrio was our car worked on. The customer already had the Agency Power exhaust system and wanted to get some more ponies, throttle response, and sound from the vehicle. So we equipped it with a ECU Flash. VRTuned does not require you to remove the ECU and possibly void your warranty. Since the cars come from the Porsche factory wanting to use 93 octane, West Coast customers that get 91 octane still can gain power. The air/fuel ratio and timing is adjusted accordingly and using the factory wideband O2 sensors to retain all knock correction and make adjustments if detonation occurs. This particular 997.2 Carrera baselined on our Mustang Dyno in AWD mode at 291 horsepower and 249ft/lbs of torque. We had to dyno the car in AWD as the cars ABS/PSM would not allow it to work with the PDK causing it to shift up prematurely without us able to manually shift through the gears. We are more concerned with the delta then the starting number. After the VRTuned Flash was done via the easy instruction manual here, we redynoed the car which put it at 310awhp and 260ft/lbs of torque. So this flash gained a true 21 wheel horsepower and 11 ft/lbs of torque. That is very good considering the ambient temperature of around 100F with 91 octane.
