Racechip GTS Black piggyback before/after W213 Mercedes-AMG E63 S M177 dyno - 710 horsepower

[Sticky]

BenzBoost tends to bring in the more hardcore AMG tuning enthusiasts but there are of course the more casual Mercedes-AMG fans who want an easy, simple, and reliable power boost. That type of customer is likely to see the appeal of the Racechip GTS Black piggyback tune.

The device certainly works as was demonstrated with before and after GPS timed pulls.

They also recently posted a MAHA dynograph for a Racechip GTS Black tuned W213 Mercedes-AMG E63 S:

There are those people out there who worship MAHA dynos so if they had any doubt the W213 E63 S is underrated that doubt should now be gone.

Baseline figures show 637 horsepower and this rises to 710 horsepower with the Racechip piggyback.

A solid gain but BenzBoost of course prefers flash tuning for all out performance.
