Updated M3/M4 From G-Power

So, you own an M3. And you think its engine doesn’t offer enough for your high skill levels. Fortunately, the G-Power tuner can increase its power to 600 hp.

What’s even more interesting is that your M3/M4 will also produce 740Nm. Now, stop imagine how fast it is, and start living at 320 km/h. All these performances are being achieved using a new ECU software which modifies the ignition diagram, the gasoline management and the boost pressure. Only the new software management raised the power to 520 hp. But this wasn’t enough, as you could expect.

The exhaust system has been totally redesigned, for a much lower back pressure. They started with the stainless steel downpipes and continued with the 100 percent titanium exhaust, for lightweight and optimized flow. In this configuration, the whole exhaust system weighs 7 kg less than the original one. Adding the new exhaust system to the remapped ECU punched an extra 40hp to an impressive 560 hp!

The trip to 600 hp continued, as the German tuner paid close attention to the turbochargers. The 30 years of experience helped them disassemble the turbochargers and optimize them by replacing the rotating parts with ones capable of moving more air while having a lower mass. The result is an obvious turbo lag reduction and an increased efficiency of the turbocharger. In the end, the revised electronic programme takes care that, with all the conversions, the M3/M4 remains a perfectly drivable car, suited for everyday life. Yet, this doesn’t mean that it’s an ordinary sports car. On the contrary, it accelerates from 0 to 100 km/h in just 3.7 seconds, partially thanks to the 295/25 ZR 21 Michelin rear tires.
