The stage 3 engine upgrade kit for the Mcchip-DKR Porsche 991 Turbo has now been revealed, and it’s a total beast. Usually Mcchip begins their project by only electronically modifying their cars. When they have eked out every last bit of juice the ECU has to offer, they set about upgrading other parts such as the turbochargers and the exhaust system.

That is exactly the case with Mcchip-DKR Porsche 991 Turbo S. The first stage of tuning is a simple chip upgrade the boosts the output of the flat-six engine from 560 horsepower to 600, and from 700 Nm to 820 Nm of torque. It’s a nice and round upgrade that gives you a top speed of 321 kmph (199 mph) and costs only 3,499.00 Euro

Stage 2 will see to it that the standard exhaust system is replaced by a custom-built unit from Capristo. This system is good for only 20 extra horsepower, for a total of 620 hp after the software optimization. But it gives the car a much nicer soundtrack, which is as good a reason as any to justify it’s whopping price tag of 10,285.00 Euro.

But the Mcchip-DKR Porsche 991 Turbo S you really want is the stage 3 which, in addition to the changes mentioned above, will replace the factory turbochargers with higher-performance, custom units. That will increase the output of the engine to 660 horsepower and 850 Nm of torque, ups the top speed to 328 km/h (203 mph), and relieves you of 17,259 of your Euros!
