Product Information
New from VR Tuned is this performance Tuning Box kit for the Mercedes C450 3.0L turbocharged engine. This tuning box kit is a plug and play solution to tune your cars fuel, timing, and boost giving you up to 40% more power and 20% fuel savings. The new C450 packs a punch producing 362bhp and 480nm of torque. With our ECU Tuning Box kit the C450 gains 80bhp and 100nm of torque over stock! Besides are European manufacturing partner testing and validating the Tuning Box, we also had a car tested State side on a Dyno Dynamics AWD dynamometer. We rate the tuning box gains at 80bhp. Typical drive train loss is about 20-25% for AWD. At 20% this would put the wheel horsepower gains at around 60 horsepower. As noted on the product this is using higher 98 octane in the UK. This car was tested in Louisiana, USA and most likely had 93octane pump fuel. Its peak all wheel horsepower gains were at 40awhp. Several variables can account for different dyno readings such as air temperature and especially fans creating a driving like scenario for the intercooler and air intake system.

Check out this great independent review from the guys at C450AMG.comon the product. The full review includes the benefits of the driving performance, what to look out for when installing, and his end result of this purchase.

With manufactures trying to increase fuel economy by adding forced induction to vehicles that previously had large displacement engines, the ability to tune them further is even more prevalent now. However there are 2 main issues with tuning these newer vehicles. The manufactures have gotten very particular about having their ECUs accessed to be tuned. These "anti tuning" features make it hard to read and write the ECU via the OBDII port. Some ECUs can be removed and flashed on the bench once the case is open. This is an immediate flag to the dealer which ultimately will void your power train warranty if a situation arose. This is where the VR Tuned Tuning Box Kits come into play over the competition.

Engineered for boosted cars, these vehicle specific plug and play kits are designed to easily be installed and uninstalled as needed. The harnesses feature OEM plugs that attach to necessary sensors where the pre-mapped tuning box gives your vehicle huge amount of performance gains. Unlike other "piggyback" solutions, these use high quality connections, wires, and casing that are designed to be engine mounted for longevity to the elements. The actual tuning box is housed in a aluminum casing that is weatherproof. These factory plug and play harnesses allow you to remove the kit as needed for warranty purposes.

Each Tuning Box Kit has been engineered and tested to work in even the most extreme environments of altitude, temperature, and driving conditions. If you have any questions in regards to the VR Tuned ECU Tuning Box Kit for the Mercedes C450, please contact one of our Performance Specialists.


  • Performance number gains are quoted based on Engine Power Gains, not wheel horsepower. Testing on the products was done in the UK using 98octane fuel. VRTuned has tested these in-house on several cars and stand behind the Tuning Box Kits work as claimed.
  • We offer support and warranty on the hardware itself.
  • We DO NOT offer a guarantee from independent dyno tests or support personal installations not done by qualified shops.

VR Tuned ECU Tuning Box Kit Mercedes C 450 AMG 270 kW 367 PS Reviews:
5 of 5 Stars! Posted on 03/23/2017 by
"I picked this unit up shortly after purchasing my C450. I agree with one of the other reviewers that the 5 minute install time is optimistic. I was done in less than 20. My only complaint with the kit is that it would have been nice to receive some guidance as to placement of the box. Otherwise I am very happy with the kit and extra happy with the result!"

"So I went to GMS Performance because I had bought the AMG C450. Don't get me wrong the car had balls when you put it in sport mode and super sport mode, I have been enjoying the car and the quickness & pep. As soon as the VIVID tune was installed I can definitely tell a difference from even an eco-mode or comfort mode the car now drives like it's in super sport mode even in eco-mode I get better gas mileage more power, the car is way faster and feels a whole lot meaner now. My first question was, why didn’t Mercedes just go ahead and tune this car like that to begin with instead of having to make me do it after market and I figured out that basically 90% of people don't need this much power in their car. I probably don't even need this much power in my car but the truth is I enjoy it, it's faster than it was, it pushes harder and at 100mph it begs for more pedal! Since having the VIVID tune installed I'm amazed how much faster the car is and better gas mileage and I can pretty much run down just about any car I want to that's stock! Next goal is to keep going fast and avoid tickets probably will get a sport exhaust as soon as I get with VIVID and GMS and see what exhaust they suggest to go with. I went with GMS Performance because I trust the owner David, he is one of the most intelligent people I know and should most likely be working on spaceships (former career prior to opening his shop) instead of cars, so I lucked out to have someone way overqualified to get the most out of my new car!"

"VR Tuning did an amazing job with this kit. Theres only a few plugs that come with the whole setup, and once you've double checked that theyre all connected properly, you go from having a fantastic MB AMG to a somehow even better MB AMG! The kit has a great pricepoint which noticeably pays off from the moment you start it up after install.. The car runs fantastic, and the direction for install were very easy to follow. VR was very easy to contact and helped us with any questions we had. Green MotorSport is proud to be apart of the VIVID Racing team."

"So...I installed the VTuned piggyback system last night. Install was not easy...Not terribly difficult either. The 5 min install time is definitely some BS. I am not a mechanic and maybe not the most mechanically inclined guy. I have installed headers, full exhaust, intakes, intake manifolds pretty much anything bolt on. This install took me about 1.5 hrs. So in the grand scheme of things still not bad. Finding a place to mount the ECU its self (which i still have not found yet) should be put in the instructions. As well as a better idea of a way to run the wires loom etc... Started car after install with no problems let the car run for about 10 mins before the drive. The drive was nice! Throttle response is better, exhaust note is a bit louder more of a growl, and I can now hear the turbos, cool plus! Car seems to be getting faster the more i drive as if the ECU is learning which is nice! Noticeable difference in acceleration. I would say aside from the install time expectation that i had based on info from Vivid, I would recommenced this to anyone looking for a quick upgrade that brings power. Nice that it comes with a jumper as well and does not void warranty. Also no engine lights triggered."

Vivid Racing has been in business since 2001 and has worked with customers all over the world. In 2005, Vivid Racing got started in the Porsche market with their 2000 Porsche 996 Carrera. In addition to building this project car with selected vendor partners, Vivid Racing also began manufacturing products through it's sister company Agency Power. Having had success in the popular tuning chassis' such as the Subaru WRX STI, Mitsubishi EVO, and BMW M3, this was a natural progression of expansion in our repertoire of vehicles.

When the recession came, Vivid Racing continued to grow and focus on the development of it's products, distribution network, and most importantly, its customers. The diversity of vehicle products and services has allowed Vivid Racing to continue to strive for excellence while maintaining exceptional growth.

With this next stage in the companies footprint, was proudly launched in January 2014.

As the tuning industries tools became more accessible, so has the ability to partner and work with individuals to offer a unique service with added value. Working with several tuning companies over the years, we have experienced the upsides and downsides of the ECU tuning world. As it is our mission to offer unparallelled customer service and support, it is equally important to offer a great product that is tested, convenient to use, and priced within reason for the current demographic. With a Mustang All Wheel Drive Dynamometer in-house at our Gilbert, Arizona facility, we have spent countless hours testing tuned files, the affects of different vehicle modifications, and learning how vehicles react to our changes. But most importantly, our product confidence comes in that we have owned these vehicles, daily driven these vehicles, raced these vehicles, and understand what the consumer is looking for.
