AMG Mercedes Tuning
Own a 4.0 V8 twin-turbo Mercedes? We've just unlocked your car's real performance potential. You can thank us later!
M177-powered AMG Mercedes models are seriously fast from the factory. Our own C63S makes over 500 horsepower and 700 Nm (516 lb-ft) of torque, enough to fire it at the horizon at a serious pace. But we know the M177 has more in it, so let us unlock the full potential of your C63, E63, GLC or AMG GT.
The research and development teams at Viezu and Paramount Performance worked together to find a safe, reliable and effective way to tune M177-equipped AMG Mercedes models. We searched the globe for a solution that met our exacting standards, and after hundreds of hours of research, on-vehicle testing and analysis, we found a tuning system we're extremely happy with.
We're delighted to add the world-renowned Burger Motorsports JB4 tuning system to our range, in its AMG Mercedes version.
It's much more than a simple "tuning box". The JB4's billet aluminum shell holds a great deal of highly advanced technology and features, including CANbus OBDII integration and fuel and spark control. The system fits between the car's sensors and its ECU and modifies the signals being processed to boost performance. After thorough testing, we firmly believe it's the ultimate tuning device for your AMG Mercedes.
JB4 AMG Mercedes Features
The JB4 for AMG Mercedes gives you enormous flexibility: switch from factory settings to full track mode, or anything in between, at the tap of a button. And yes, you can control it wirelessly from any compatible iOS or Android device. A Windows laptop also works with the optional data cable, but we strongly recommend the mobile app for convenience and a great user experience.
*App purchase required.
Because it's essentially plug and play, installation is very easy to reverse. Take the JB4 out and your car is fully back to factory specification, or use the companion app to return to factory settings temporarily. A big advantage over an ECU remap is that a dealer software update can't wipe your map.

Power
The JB4 delivers seriously impressive gains of around 100 hp and 135 Nm (100 lb-ft) of torque. Our in-house testing shows those figures are very achievable, depending on the individual car and the fuel quality.
As part of our extensive research and testing, we ran a C63S on our highly advanced 3,000 horsepower four-wheel-drive rolling road several times. Before installation, our factory-spec C63S made 514 horsepower and 730 Nm (538 lb-ft). With the JB4 fitted, we saw reliable, significant gains: a massive mid-range increase of 110 hp and 175 Nm (129 lb-ft). You'll definitely feel gains like that, on the road and on the track.
Reliability
We only sell products we believe in. Adding the Burger Motorsports JB4 to our range follows hundreds of hours of research and testing, including thorough dyno work and hundreds of miles of road driving before it launched in our shop.
Mail Order
We ship items from our shop worldwide.
We recommend professional installation, but if you're a competent home mechanic or want your preferred tuner to fit it, just add the tuning box to your cart.
