VR Tuned ECU Flash Tune Mercedes GL500 | GL550 5.5L V8 X164 388HP 07-12

The Mercedes-Benz GL500 | GL550 5.5L V8 is a great SUV to drive. This power and performance make the GL a top choice for a family vehicle. But what you need is more power! The VR Tuned upgrade adds more horsepower and torque over stock. With our ECU flash, you are able to gain improved performance on the engine. The biggest difference when you flash your SUV is the overall improvement of the power curve. Your SUV will have much better throttle response and pull all the way to redline. Where your SUV is sluggish off the line, your newly flashed SUV 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 SUV craves for.

How to Flash Your ECU?

• Use the DimSport handheld device. This REQUIRES a Windows PC.  You can flash between these at anytime.  See Instructions Here.
• Bring your vehicle to our facility where we can use our Master Cable to flash your vehicle.
• 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.

For reference this ECU is a Bosch ME9.7.
