• Note: To get the maximum performance out of this ECU flash, please tighten your wastegate rod down to limit the travel. The factory wastegate is very soft and weakens over time. The ECU calls for more boost pressure but the wastegate will not allow for this without adjustment.

What are the benefits of VR Tuned?

• #1 priority is our customer service to you!
• Our tuning is used worldwide. 
• Basic bolt-on performance parts will not require a retune of your ECU. Other efficiency parts such as colder spark plugs, boost tubes, or diverter valves are not required but can help performance.  The ECU will adapt to these changes.
• We can tune cars worldwide including JDM, EU, Australian, and USA cars for different types of octane or environments.
• We do not lock, "pot", or keep control of your ECU.  If you decide to take it to another tuner for an upgrade, all flashing ability is retained.

How to Flash Your ECU?

• We can bench flash your ECU. To bench flash the ECU, you must remove it from your vehicle and send it to us (See Instructions Here).  You can also send us a new ECU to be flashed. 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.
• Bring your vehicle or ECU to our facility where we can do the ECU Upgrade here.
• Order our OBDII Flash cable to be able to flash between a stock and your tuned file.  See Instructions Here
