    • Weistec releases their tune for the M157 bi-turbo 5.5 liter V8 in 63 AMG models - +149 wheel horsepower for $2950

      Weistec Engineering has released their M157 tune for Mercedes 63 AMG vehicles. The tune adds an incredible 149 wheel horsepower and 193 wheel torque. These gains come on 91 octane and to this point nobody has shown more horsepower on 91 octane pump gas tune only on the M157 platform. In addition to the horsepower gains the top speed limiter is removed, throttle maps are changed for better response, and boost, fuel, and spark are all adjusted. Check out the product page to order or for more info: http://weistec.com/m157s1.html

      This tune is available for standard M157 vehicles or for those with the optional Performance Package. Gains with the Performance Package are less at 106 wheel horsepower due to the tune being more aggressive from the factory.
