However, for the guys at Renntech it appears that nothing can be too extreme. The Florida tuner has set about boosting the output from the already high-strung engine – lifting power by 43hp (32kW) to a new peak of 550hp (410kW). Peak torque also rises by 59lb-ft (80Nm). To achieve the bump in performance, engineers added a recalibrated ECU, long-tube headers and a high-flow exhaust system.
"Real-world performance is all about torque, not so much about a peak horsepower number at very high rpm," explains Hartmut Feyhl, company founder. "It can be very easy to build high rpm horsepower, but to get instant throttle response and mid-range acceleration it is more difficult, and this is where customers really want to feel that improvement."
With the added power, the car will now accelerate from 0-62mph (100km/h) in less than four seconds and reach a top speed in excess of 186mph (300km/h).
Renntech has also replaced a lot of the standard plastic and metal trim details with new carbon-fiber pieces, including the front splitter and new diffuser. There’s also a custom sports suspension set-up with carbon-fiber struts and fully-adjustable camber bushings at all four corners.

Will the horsepower wars never end???
Not that I wouldn't love to smoke a track with
one of these, but really, did any of the AMGs
ever need more power???
