The 991 GT3RS is the first GT3 variant that does not come in a manual transmission, but with the PDK, it is still one incredible street/track car. As you rev past 2000 rpms, the exquisit sound coming from the back of the car is a like a symphony of horses ready to trample anything in its path. Jumping up from the previous 997.2 3.8L GT3RS, the 991 GT3RS shifts in milliseconds while it delivers 500 horsepower at 8250 rpms. 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.

How to Flash Your ECU?

• Use the Alientech Powergate 3+ handheld device. This device is a touchscreen module that lets you store your original and tuned files to easily flash between them. See Instructions Here.
• We can bench flash the ECU. To bench flash the ECU, you must remove it from your vehicle and send it to us. Once we receive the ECU, we will prepare the tune file and then send it back to you for reinstallation.
• Bring your vehicle to our facility where we can use our Master Cable to flash your vehicle.

For reference, this ECU is a Bosch MED17.1.1.
