Weistec ECU tuned M157 2012 CLS63 AMG takes on a Powerchip tuned C63 AMG
Wesitec recently released their M157 tune
and here we get to see it in some real world action. The CLS63 AMG straight up destroys the C63 AMG and this is not much of a race. The CLS just puts bus lengths on the C63 practically instantly. In the defense of the C63, the Powerchip tune is one of the weakest available for the M156 platform and rumors are that Powerchip is not even a functioning business any longer (more on this at another date). The Weistec tuned car is so strong though that it really would not matter what tune the C63 was running although it would have at least been a better fight with a different tuning option.
