G-Power Offering Potent Upgrade For Your BMW M4 GTS

The BMW M4 GTS will only get a 700 unit production run worldwide and although it already costs double the amount of a regular M4, G-Power are now offering a tuning package for the track-honed German machine. G-Power did more than just an ECU tune for their car as they have pumped up the power from 500 to 615 horses. G-Power customized the turbine wheel and housing of the turbochargers as a start and then added a more free-flowing exhaust to reduce backpressure so a set of stainless steel downpipes without catalysts were fitted. Obviously the ECU has been remapped too thanks to the Bi-Tronik 2 V3 kit resulting in the 615 hp figure. Torque has also been dramatically increased from 600 Nm to 760 Nm. Now when you launch this thing, you are able to hit 100 km/h front standstill in just 3.6 seconds and go on all the way to 320 km/h. If you like you can also slap on a set of lightweight 21-inch wheels. For owners not wanting to mess with the engine’s internals, an ECU-only tune is offered, resulting in 575 hp and 740 Nm.
