Mercedes-Benz SLS AMG by Kubatech

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.

Porsche 911 (997) GT2 by Kubatech

German tuner Kubatech has a tuning kit that provides an update for the aging Porsche 997 GT2 model.

Although this tuning job takes place strictly under the hood it involves a complete revision of the 3.6 liter turbo unit.

The engine tuning kit includes modified turbochargers, performance charge air coolers, 200-cell sport catalysts from Cargraphic, new manifolds as well an an ECU remap. The so-called Stage 3/MC650 kit dials up power on the 3.6 liter turbo to 657 PS (483 kW / 648 bhp) and 835 Nm (616 lb-ft) of torque. A substantial upgrade from the series 530 PS (390 kW) and 680 Nm (501 lb-ft).

The job, says the tuner, takes six to eight working days to do and costs just under €23,000.

Porsche Carrera GT Stage II by Kubatech

German tuner Kubatech has a Stage II tuning package for the currently discontinued Porsche Carrera GT.

Kubatech refers to itself as an engine software specialist and it is mainly through an ECU optimization that it dials up the power on the Carrera GT's 5.7 liter V10 engine from a standard 612 PS (450 kW) to 660 PS (485 kW). Torque also gets a bump to 642 Nm from the series' 590 Nm.

Also added is a Cargraphic sport exhaust system made of high-grade steel that makes for upgraded numbers on the Carrera GT. The Stage II's top speed is now 343 km/h (213 mph), compared to the previous 330 km/h (205 mph), and the 0 to 100 km/h sprint time is improved but Kubatech does not specify by how much.

Stage II tuning of the Porsche Carrera GT by Kubatech comes at an all-included cost of €10,699.
