    • Weistec kicks off Mercedes M256 I6 tuning with catless downpipe and ECU software - 53 AMG modes, W213 E53

      You are going to see M256 tuning pick up as more Mercedes models roll out with the motor. This is the new Mercedes modular engine architecture which is very similar to what BMW, Porsche, and basically all German OEM's are doing to cut cost by sharing engine parts among various displacements.


      The W213 E53 AMG sedan and the C238 E53 AMG coupe variant both have this motor. Output is 429 horsepower stock and Weistec can raise this by 43 horsepower and 90 lb-ft of torque.

      Add in the catless downpipe and output goes up by 58 horsepower and 105 lb-ft of torque.
