Although there are people out there who don’t like the M5, there is no denying that it has borderline supercar performance. The twin-turbo 4.4L V8 under the hood of the F90 is an evolution of the previous M5’s engine, and this time around it has new turbochargers which make 24.5 psi compared to 21.8 psi in the last M5. Outputting 600 horsepower and 553 ft-lbs of torque, most people would say that’s plenty of power. AC Schnitzer, one of the biggest names in the BMW aftermarket, has just released their new tuning system which will allow F90 M5 owners to easily and safely increase power.
This tuning system from AC Schnitzer works by taking sensor signals such as boost pressure and air/fuel ratio and modifies the signal before sending it to the ECU. This effectively tricks the ECU into thinking it’s not making enough power, so it cranks everything up to compensate. Since it’s making the correct amount of power to begin with, the system effectively tricks the car into making more power. In this case, it takes the F90 M5 from 600 horsepower to 700 horsepower. Torque is also increased from 750Nm to 850Nm. These gains not only make your M5 faster overall, but that big jump in torque will make it much more fun to drive on the street.
