Maxi-Tuner is a German tuning company that decided to offer a power kit for the Porsche 911 Turbo as well as the S version. As a reminder, the stock engine powering these two models is a 3.8-liter producing 520 hp or 560 hp, depending on the version.
However, if these standard figures don’t make you happy, Maxi-Tuner has the solution. The Porsche 911 Turbo gets a power boost of 60 horses to a total of 580 horsepower and 760 Nm of torque while the S version will deliver 620 horses and 800 Nm of torque.
