G-Power has recently upgraded its power boost kit that they have developed for BMW M6 Coupe F13.
The G-Power Bi-Tronik III package is now in its second version and now the twin-turbo V8 4.4-liter engine delivers a revised and upgraded output of 710 HP (522 kW) and 890 Nm (656 lb-ft) of torque as compared to 560 HP (412 kW) and 680 Nm (501 lb-ft) of torque in stock model. The first version that was released by G-Power came with an output of 640 HP (471 kW) and 777 Nm (573 lb-ft) of torque.
In order to increase the output, G-Power has remapped the ECU and installed a new exhaust system with titanium link pipes which is 12 kg (26.4 lbs) lighter than the stock exhaust. The tuner is offering this exhaust system with four titanium or carbon 100mm tailpipes. With the revised output, the car will be able to achieve the 0-124 mph (0-200 kmph) sprint in just 10.8 seconds before touching the top speed of more than 186 mph (300 kmph).
In terms of pricing, the power boost will cost 17,985 EUR and an extra 14,460 EUR for the ceramic braking system. The wheels and tires combo would cost 8,325 EUR and the coilover suspension would cost an additional 2,179 EUR.
