Renntech, a renowned aftermarket tuning company focused on Mercedes-Benz vehicles, just released a new kit for the Mercedes-AMG SL 63 that puts its power near the level of the Mercedes-AMG GT 63 S E Performance.
According to Renntech, the latest tuning package for the AMG SL includes an ECU tune with new throttle mapping, modified ignition timing, and optimized air-to-fuel ratios. Professional installation is recommended by the specialist, and it claims that the tune can be easily reverted back to stock.
Performance Upgrade
The upgrade brings a significant power increase to the AMG SL 63, taking its horsepower to 721 and torque to 748 pound-feet. This means a whopping 144 hp and 158 lb-ft boost on the stock configuration of the base car.
It should be noted that the base model of the AMG SL 63 already produces 577 horsepower and 590 lb-ft of torque, allowing it to sprint from 0 to 62 mph in just 3.6 seconds and reach a top speed of 196 mph. Although Renntech does not mention the resulting acceleration time of the tuned roadster, it’s guaranteed to cut the car’s original 0-62 mph sprint time significantly.
Pricing
The package costs $3,840, excluding taxes, in the United States. This seems like a fair price considering that the new AMG SL 63 base model costs $178,100 before the destination charges, dealer fees, and optional equipment.
Conclusion
Overall, Renntech’s new tuning package is an attractive option for those who want to boost the performance of their Mercedes-AMG SL 63. With its increase in power and torque, the car is definitely a force to be reckoned with on the road.
