For Mercedes-Benz enthusiasts who love big-bodied two-door coupes, but also want the luxury of a convertible top, the SL550 (SL500 in the rest of the world) is the go-to car. Outputting 435 horsepower, it has the power to take on lots of powerful sports cars, but still falls short of the SL63. If you want to close the gap between SL550 and SL63, more power is a necessity.
Thanks the Mercedes’ use of twin turbos on the S550’s 4.7L V8 engine, there is a lot of room for improvement. The best way to maximize the power potential is with ECU tuning. Even with modifications such as an intake and exhaust system, power can’t be fully realized without tuning.
In the case of the S550, our VR Tuned ECU flash modifies ignition timing, fueling, boost, throttle limiters, torque limiters, and more. Our tuning increases power without sacrificing long-term reliability or drivability. On top of the power increase, throttle response and fuel economy are improved.
- Stock Power: 435HP and 516 LB-FT
- Tuned Power: 460HP and 561 LB-FT
- Improved Throttle Response
- Works with Additional Modifications
