VR Tuned ECU Flash Tune Porsche 991 R 4.0L 500hp 2017

The 991 R is the road going version of the GT3RS but in a manual transmission. With the same 500 horsepower as the GT3RS, ECU tuning is available to enchance the vehicles performance.. The VR Tuned ECU flash was developed to focus on improving the cars entire power curve. With our Stage 1 calibration, the throttle response is much quicker and the low end torque comes to life faster. The PDK transmission is controlled seperately, but you will notice the gears hitting harder and faster with the increase in torque. With this flash you can expect to see your lap times improve with faster corner exit speed, top speed, and improved driveability.
