The 991.2 GT2RS is simply the best street legal 911 made. The 3.8L twin turbocharged vehicle makes 700hp which is a lot considering the car weighs only 1470kg. Never doubt a limit as turbocharged vehicles always have more room to lend. The VR Tuned ECU flash was developed to focus on improving the cars entire power curve. With our ECU calibration, the throttle response is much quicker, with turbos spooling faster. The huge increase in torque and horsepower will have your mind simply blown away. With this flash you can expect to see your lap times improve with faster corner exit speed, top speed, and improved driveability. 

Our test vehicle was run on our Mustang AWD dyno in 4th gear from 2500-6500.  Test in June with a room temp of around 105F here in Arizona, we were still able to make very impressive gains with a fuel mix to 93-94 octane.  The car made about 640awhp and 690ft/lbs of torque to the wheels.  With typical drivetrain loss on a Mustang AWD dyno of 20-25%, these are VERY impressive numbers!

Crank Horsepower Ratings:

• Stock Power: 700HP | 553FT/LBs
• Tuned Power: 800HP | 850FT/LBs

How to Flash Your ECU?

• Use the DimSport handheld device. This REQUIRES a Windows PC.  You can flash between the stock and tuned at anytime. See Instructions Here.
• Bring your vehicle to our facility where we can use our Master Tool to flash your vehicle via the OBDII port.
• 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 ship it back to you for reinstallation. We do not solder or modify the ECU board at all. All ECU tuning is done via bungy probes that have a needle tip to provide an electrical connection.

Options:

• We have a Stage 1 flash for 91octane and a Stage 2 flash for 93+ octane.  You can select to get both of these if you using our OBDII tool after the ECU is unlocked.

For reference, this ECU is a Siemens SDI21.
