Posaidon is a German tuner and they recently introduced a power kit for both the Mercedes-AMG GT and C63. These cars share a 4.0-litre twin-turbocharged engine so it makes sense for the package to work on both models. In the AMG GT, you can bump things up to 455 hp and 600 Nm while in the AMG GT S it can be pushed to 503 hp and 650 Nm of torque. If you want to go a step further, you can get boosted all the way up to 620 horses and 725 Nm of torque and this can be applied to both engine versions. The C63 and C63 S can gain increases all the way to 600 horsepower and 800 Nm of torque, These are some potent figures for already potent cars but someone will most definitely do this to their new German performance machine.
