    • Solo Motorsports Stage I W205 Mercedes-AMG C63 M177 4.0 liter twin turbo V8 Mustang dyno tune results

      Great to see some Mustang dyno figures from a stock and tuned M177. This particular twin turbo 4.0 liter AMG V8 is in a W205 C63. This is the standard version rated at 469 horsepower and 479 lb-ft and not the higher powered C63 S.


      Frankly, it is only software that separates the output of the two and that is what makes the standard C63 a tuning value as you can easily get C63 S output and more with a good tune:


      The baseline is 378 rear wheel horsepower and 420 lb-ft of rear wheel torque.

      With just the SMS Stage I tune on pump gas output rises to 461 at the wheels for a gain of 83 horsepower at the wheels. The torque increase is just under 100 lb-ft with a gain of 95 lb-ft at the wheels.

      The majority of the torque gain comes at 2700 rpm to 5000 rpm but you see gains throughout the entire curve.

      M177's respond very well to tuning as you already know.

        And now they just discontinued the non-S C63 here...

        They probably find most just opt for the S.

        Thanks, typo fixed.
