The Mercedes-Benz SLC43 featuring the 3.0L Bi-Turbo engine is a blast to drive. The VR Tuned ECU upgrade adds more horsepower over stock. 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.

What are the benefits of VR Tuned?
#1 priority is our customer service to you!
Our tuning is used worldwide. We have powered vehicles of all types.
All ECU tunes can be reverted back to stock if necessary.
With the VR Tuned ECU Flash, basic bolt-on performance parts will not require a retune of your ECU.
Adding parts such as an exhaust, intake, plenum, pulley, will all adjust with the tune.
If you add higher octane fuel, the ECU will adjust accordingly.
We can tune cars worldwide including JDM, EU, Australian, and USA cars for different types of octane or environments.
Other custom enhancements are available if requested and applicable.
We test and dyno tune on our own cars to make sure what you get is safe, reliable, and gives you the results you want!
How to Flash Your ECU?
Use the Alientech Powergate 3+ handheld device. This device is a touchscreen module that lets you store your original and tuned files to easily flash between them. 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 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.
