    • The most powerful Mercedes-AMG GT - GAD Motors 946 horsepower Stage IV M178

      946 horsepower and 902 lb-ft of torque puts this C190 Mercedes-AMG GT S ahead of any other AMG tuner BenzBoost is aware of. GAD Motors says this car has their Stage IV package and what that means or what it costs is anyone's guess.


      As is how they are keeping the transmission together. Several AMG tuners are not pushing their M178 turbo upgrades as hard as they could due to not wanting to exceed the OEM dual clutch gearbox capacity.

      As for the dyno output itself, the Superflow can be set to read output at the wheels or corrected to the crank and this definitely appears to be crank output:


      It would be nice to receive more details and a whp graph from GAD but this is likely the best we will get.

      Incredible work regardless.
