VR Tuned ECU Flash Tune Mercedes GL63 S AMG 5.5L V8 Bi-Turbo 577HP

The Mercedes-Benz GL63 S featuring the 5.5L Bi-Turbo engine is a pure animal directly from the factory. However once you do the the VR Tuned ECU upgrade, the GL63 becomes a supercar killer. With our ECU calibration, you are able to gain improved performance from the engine with an increase in horsepower and torque. The biggest difference when you flash your car is the overall improvement of the power curve. Your car will have much better throttle response and the turbos will spool up faster. Where your car is sluggish off the line, your newly flashed car picks up right away and pulls harder through the mid and top end RPM range. Overall, the driving characteristics are vastly improved while providing you additional benefits that your car craves for.

How to Flash Your ECU?

• Use the DimSport handheld device.  You can flash between these at anytime.  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 ship it back to you for reinstallation. We do not solder or modify the ECU board at all. All ECU tuning is done by plugging into the front connecting pins.
• Bring your vehicle to our facility where we can use our Master Cable to flash your vehicle.
