Product Overview

The revised M177 engine in the W213 E63 and E63-S models(S63 models as well) is quite the step up from the M177 in the W205 C63(S).? The twin scroll turbos offer improved top end compared to the C63(S) and generally more power straight from the factory.? That does not mean we weren't able to get more power out of it!? Our Tune for the W213 E63S provides solid gains through out the entire powerband, with peak to peak gains of more than 50HP* and mid range gains of as much as 75HP*
