BenzBoost does not know whether the car is using the Weistec base tune for the 3.0 liter supercharger upgrade that is modified by Eurocharged or a ground up tune from Eurocharged. Considering that Eurocharged has control of the M113K V8 to the degree necessary to ditch the factory supercharger and do a twin turbo setup either scenario is possible.
Regardless, a very quick Mercedes that shows what a lighter chassis (although this is a full weight car, not stripped) is capable of with the supercharged M113K. The 1.518 60 foot also shows the car is hooking very well. This is about it's maximum potential at the current power level unless it runs in better DA. Video of the run below.
