The chained monster you see above is a Porsche 911 (991) Turbo S freshly tuned by Mcchip-DKR and strapped to the dyno machine to reveal how much power it makes. The tuner offers a couple of stages of upgrade for the flat-six engine in this car, the most potent of which is good for an extra 100 horsepower.

The stage 1 of Mcchip-DKR Porsche 991 Turbo S tuning program increases the output of the 3.8 liter flat-six twin-turbo engine from 520 hp/660 Nm to 580 hp with 800 Nm of torque. That is a healthy gain, considering it’s just electronic modifications.

Throw in a Cargraphic sport exhaust with sport catalysts and flap system to the mix, and the previous kit will give you 600 horsepower and a top speed of 323 km/h, which is 8 more than the standard. The cost of all this is around 3,500 Euros.

But the program you really want is Mcchip-DKR Porsche 991 Turbo S stage 2, which includes a beefier software optimization plus the aforementioned sport exhaust system. This package costs a whopping 10,000 Euros, but it delivers 620 horsepower and 820 Nm of torque.
