Posaidon has just released not one but two incredible tunings of Mercedes C63 AMG and AMG GT models. There is one common thing about those two and it is that they are powered by the 4.0-liter twin-turbo V8 engine. The difference is in the nature of their lubrication. Precisely, the AMG GT has dry sump lubrication, while the other car utilizes a conventional wet sump system. Well, there is another thing in common and this is the direct re-programming delivered by Posaidon.

The standard output of the two-seater is 462 hp (340 kW) and 600 Nm (443 lb-ft) of torque, while its more powerful S version produces 510 hp (375 kW) and 650 Nm (480 lb-ft). After the conversion, both cars are capable of 630 hp (463 kW) and 725 Nm (535 lb-ft) of torque and a 337 km/h top speed.

In addition, the standard numbers of the C63 AMG are as follow: 476 hp (350 kW) and 650 Nm (480 lb-ft) and 510 hp (375 kW) and 700 Nm (517 lb-ft) in the S form. After the ECU, they were changed to 610 hp (449 kW) and 800 Nm (590 lb-ft) of torque. The top speed here is positioned at 328km/h.

The engine of the C-Class is mated to an AMG SPEEDSHIFT MCT 7-speed sports transmission, while this of the AMG GT to an AMG SPEEDSHIFT DCT 7G dual-clutch transmission, which explains why the torque of the latter car is lower.

Furthermore, Posaidon engineers are currently working on additional updates for the M177 and M178 engines. For their improvement they will use new turbochargers, free-flow exhaust systems and other hardware changes. At last, for additional safety, the tuners offer speed camera warning system which is integrated within the factory navigation system.
