German aftermarket specialist Maxi-Tuner has launched a power boost program for the Porsche 911 Turbo and 911 Turbo S (991 generation).
Developed for those who are hard to satisfy, the tuning program is addressed to the 911 Turbo and 911 Turbo S which share a direct-injection, 3.8-liter six-cylinder engine. In its standard configuration, the engine delivers 520 HP (383 kW) and 660 Nm (710 Nm with overboost) in the 911 Turbo and 560 HP (412 kW) and 700 Nm (750 Nm with overboost) in the 911 Turbo S.
It should be enough for most people but that hasn't stopped Maxi-Tuner from remapping the engine's ECU (€1,899) which boosted output further. After the software tweaks are implemented, the engine packs an extra 60 HP (44 kW) and 100 Nm (74 lb-ft) so it delivers 580 HP & 760 Nm in the 911 Turbo and 620 HP & 800 Nm in the 911 Turbo S.
Maxi-Tuner is also offering a custom stainless steel exhaust system (€1,990) which has been installed on the 911 Turbo S depicted in these images and has bumped output to a grand total of 635 HP (467 kW) and 864 Nm (637 lb-ft) of torque. They did a performance test and managed to run the 0-62 mph (0-100 km/h) in just 2.8 seconds, making it 0.3s quicker than the 911 Turbo S with Sport Chrono Package. Top speed was also increased by 10 km/h (6.2 mph) to 328 km/h (203.81 mph).
