Twin-turbo fun time!

The new Mercedes-AMG branch of high-performance vehicles knows how to bring the power. The new Mercedes-AMG GT / GT S and C 63 / C 63 S are two examples of pure German muscle and bring a considerable amount of adrenaline into the lineup. The team at POSAIDON took both sports cars up a notch with their new simple yet effective tuning programs.

Both the Mercedes-AMG GT and C 63 utilize versions of the new AMG 4.0-liter, twin-turbocharged V-8 engine. One of the differences between the two engine variants in the two models is that the M178 variant in the AMG GT has a dry sump lubrication system while the M177 in the C 63 utilizes a wet sump lubrication system.

POSAIDON has developed a new tuning program for both M177 and M178 engines for each model to produce more power without the need for additional auxiliary modules inside the engine bay.

The Mercedes-AMG GT and GT S models with 456 horsepower and 503 horsepower, stock, respectively, gain a considerable amount of power with the new POSAIDON tune. After the re-programming, a total of 630 horsepower and 535 lb-ft. of torque is available with a press of the throttle for both variants. This allows the new German sports car to reach a top speed of 209 mph.

With the four-door sibling, the Mercedes-AMG C 63 and C 63 S models with their 469 horsepower and 513 horsepower outputs also get a pretty big boost. The POSAIDON tune gives the twin-turbocharged V-8 a total of 610 horsepower and 590 lb-ft. of torque. That’s good for a top speed of 204 mph as well.

The contrast in torque numbers between the two models after the POSAIDON tune can be attributed to the different transmissions. The AMG SPEEDSHIFT DCT 7G dual-clutch gearbox in the AMG GT / GT S has a lower torque capacity compared to the AMG SPEEDSHIFT MCT 7-speed sports gearbox found in the C 63 / C 63 S. Therefore, more torque can be unleashed in the sedan.

As part of the new POSAIDON reprogramming, both models will allow drivers to disable the ECO start-stop function in any driving mode instead of just the factory Sport and Sport+ modes. An optional speed camera warning system integrated into the factory COMAND Online system or Garmin MAP pilot navigation systems.
