Which engine gains most?
The 5.5 AMG V8 twin-turbo, by a clear margin. The naturally aspirated 6.2 gains considerably less, since there is no boost to adjust.
Why so many speed limiter removals?
These cars carry an electronic cut set at 250 km/h. Note that legal speed limits on public roads are unchanged by any electronic work.
Is the work reversible?
Yes. We always keep the original ECU file, so the car can be returned to its factory configuration.
