VR Tuned ECU Flash Tune Mercedes SLK55 5.5L V8 R172 421HP 12-16

Your Mercedes-Benz SLK55 5.5L V8 is a load of fun to drive. This roadster is awesome in its power delivery and performance. The VR Tuned upgrade adds more horsepower over stock. With our ECU flash, you are able to gain improved performance on the engine. The biggest difference when you flash your SLK is the overall improvement of the power curve. Your SLK will have much better throttle response no matter what gear you are in. Where your SLK is sluggish off the line, your newly flashed SLK picks up right away and pulls harder through the mid and top end RPM range.

How to Flash Your ECU?

• 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.
• Bring your vehicle to our facility where we can use our Master Cable to flash your vehicle.

For reference this ECU is a Bosch MED17.7.1.
