So far almost all the performance kits we have come across for the F80 BMW M3 and M4 were rated at around 520-something horsepower. While that’s good, having more is always better. That’s why G-Power came up with a new program that gives you a nice and round 600 horsepower.

Building on their previous tuning programs for BMW M3/M4, G-Power has altered a few parameters of their “Bi-Tronik 2 V3” ECU map, changing ignition timing, fuel and boost pressure. Before they apply these changes the program was good for 520 hp. Afterwards, it churns out 600 horsepower and 740 Nm of torque. Of course, we shouldn’t forget the role the flow-optimized downpipes and exhaust system with 4-tip sport silencer and link pipes with resonators play in the whole thing.

Now, the horsepower figure is absolutely meaningless unless you can provide some solid performance numbers to back it up. G-Power BMW M3/M4 cover that nicely, as they boast a serious turn of speed. With the 600 hp package installed, you are looking at acceleration from zero to 100 km/h in 3,7 seconds and a top speed of 320 km/h. As usual, the visual treatment for G cars are limited to a set of wheels, in this case 21-inch HURRICANE RR forged alloy wheels shod with 245/30ZR21 and 295/25ZR21 Michelin tires.
