When you own an older BMW M3 E92, you won't have to be afraid that tuning companies don't want to tune your car anymore. The only BMW M3 with a V8 already got a supercharger from G-POWER before but they decided to take another look at the car. The result is a great power boost.
630 hp and 590 Nm of torque is the result when you bring your BMW M3 to G-POWER. That's an extra 20 hp than before and an extra 210 hp compared with the standard M3. For 1.600 euros you can boost your power 20 hp. I don't know if that's really necessary but with a standard M3 your power will gain 210 hp for 'only' 20.000 euros. You can sprint to 100 kph in four seconds and you will have a top speed over 330 kph.
