German tuner takes output past the 608 HP expected in the upcoming SLS AMG Black Series.

German tuner Kubatech has a new power upgrade package for the SLS AMG Gullwing.

The tuner, working with Mcchip-dkr, has developed a software-based optimization kit for the SLS AMG that dials output on the 6.3-liter (6,208cc) V8 engine to 625 PS (460 kW / 616 hp) and 680 Nm (501 lb-ft) of torque over the series 571 PS (420 kW / 563 hp) and 650 Nm (479 lb-ft) of torque.

That's 17 PS more than the 608 PS (447 kW / 600 hp) expected in the upcoming SLS AMG Black Series and in full compliance with what is allowed by Mercedes-Benz.

Total cost for the upgrade is €8026.
