Your Mercedes-Benz C350 3.5 V6 is a load of fun to drive. The VR Tuned upgrade adds more horsepower over stock. With our Stage 1 calibration, you are able to gain improved performance on the engine. The biggest difference when you flash your car is the overall improvement of the power curve. Your car will have much better throttle response no matter what type of transmission you have. 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.

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, pulleys, will all adjust with the tune. If you add higher octane fuel, the ECU will adjust accordingly. We can tune both EU and USA cars for different types of octane or environments.

What are the benefits of VR Tuned?

• #1 priority is our customer service to you!
• Our tuning is used worldwide. We can provide you a tuned file no matter the octane you get or the environment you live in.
• 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!

NOTE: Upon ordering of this ECU Flash Tune, you will be required to send in your ECU. Once we receive the ECU and program it, we will ship it back to you via the method you select at checkout. This ECU cannot be flashed via the OBDII port unless you come to our Arizona location. This requires the ECU to be mailed in to us to be benched flashed. Bench flashing requires the ECU to be opened. We DO NOT solder or modify your board in any way. Using a electrical contact pins, we tie into the boards programming mode to read and write the file. We do store your stock file if you ever want to revert. Because the ECU must be removed and opened, if you are concerned with warranty, you may want to speak with your dealership. Anytime you add higher octane, the fuel will burn slower providing your vehicle with improved performance. We never recommend using leaded gas such as C16 as this will destroy your O2 sensors and catalytic converters.
