This stunning facelift C63S AMG with updated 9 speed transmission was delivered to us with #dyneperformance downpipes fitted by our friends at IT Mechanical. With the upgraded downpipe and stock ECU tune, it produced a baseline run of 314rwkw/427whp.
An #Etuners tune was loaded and custom calibrated. Peak power rose to 379.6rwkw/516whp, a gain of 65kw/88.4whp and a massive 80kw/109whp gained in the mid range.
