How much does the 4.0 AMG V8 take?
It is a twin-turbo V8 with substantial headroom, even from a high factory output. Stage 1 works with standard hardware.
Why is Stage 2 dominant here?
These cars are frequently modified by their owners, typically with exhaust hardware, and Stage 2 is what takes advantage of it.
Why so many speed limiter removals?
These cars carry an electronic cut. Note that legal speed limits on public roads are unchanged by any electronic work.
