AC Schnitzer module fitted to a G20 M340i xdrive

What a difference it has made. At first, my expectations were that the gains made would be subtle. But I was wrong.

The module made a very noticeable difference.

In terms of acceleration, what was comfort mode now feels like sport. And sport is now a whole other level.

What is instantly noticeable is the improvement in mid range acceleration. The additional torque of 100 Nm can certainly be felt through the car's acceleration. From a rolling speed of 50mph, when you open up the throttle, acceleration is much improved.

The car was always fun to drive as a daily, and now it's just at another level of driving pleasure.

Thanks Daniel & Lorcan.
