2010 997.2 Turbo ECU Flash Tested – 50awhp Gain! VRTuned.com June 1, 2010 Product Info, Tuning Tech We testing the VRTuned ECU Flash on a 2010 Porsche 997.2 Turbo. The car was a PDK running on 91octane fuel with an ambient temperature of about 95F outside. From the factory, the car comes with 500 horsepower to the crank and our baseline done 4 days prior was at 435awhp. Typically the Mustang AWD Dyno has about a 20-25% drivetrain loss when tested. 20% of 500 is 400whp and this car definitely exceeded that. Is it possible the 500HP rating is “underated”??? Whatever the case, once we flashed the 997.2 Turbo through the OBDII port, the car gained 50 all wheel horsepower and 54ft/lbs of torque bringing the car to 486awhp and 501 ft/lbs of torque. This test was also done with a stock exhaust system which is usually extremely restrictive. Stock exhausts generally produce alot of backpressure giving torque spikes. An aftermarket exhaust would gain another 20whp approximately. What you can tell from this dyno is that the performance from the VRTuned ECU flash gives a huge improvement in the daily driving rpm range. Peak performance comes on at about 3300rpm and holds strong to 4700rpm where the power then stays consistant to redline. Check out the pictures and video below!
