    BMW M3 G80/G81 owner? BMW M4 G82/G83 owner? BMW M2 G87owner? We just unlocked the true performance potential of your BMW M car! You can thank us later!

    We don’t deny the S58 powered BMW M cars are seriously potent vehicles from factory. The G80 M3 combines well in excess of 500 horsepower and 650 Nm of torque to propel itself from 0-62mph in just shy of 4 seconds. That said, we know the S58 has more to give! Let us unlock the true potential of your M2/M3 or M4.

    The ECU in these vehicles is currently locked, so it is not possible to perform a custom remap at this time. This would normally involve writing a modified file for the vehicle with updated parameters, which is then loaded back into it’s ECU. If you would like to learn more about different tuning methods please take a look at this informative blog from our friends at VIEZU.

    With this limitation in mind, the research and development team at Paramount Performance have been working in partnership with the software tuning wizards at VIEZU to find a safe, reliable and effective tuning method for the S58 equipped M2, M3 and M4. We have scoured the globe for a tuning solution that meets our high standards, and after hundreds of hours worth of research and on vehicle testing and analysis, we have found a tuning system we are extremely happy with.

    It is our pleasure to add the world renowned Burger Motorsports JB4 tuning system to our product range.

    This advanced device is a lot more than a simple “tuning box”. A huge amount of extremely advanced technology lies within its billet aluminium shell. The system includes highly advanced features such as CANbus OBDII integration, as well as fuel and spark control. The system installs between the cars sensors and it’s ECU and modifies the signals being processed to improve performance. Following thorough testing, we strongly believe it to be the ultimate tuning device for your S58 powered G80/G81 M3, G82/G83 M4 or G87 M2.
