BMW X6M tuning will drastically change the performance of the already beastly 4.4L twin turbocharged engine. Coming stock with 555hp to the crank, the stylish SUV is no soccer mom car. With its M suspension and larger BMW brakes, the X6m does 0-60 in just 4.5seconds! More power is easily obtainable with the VR Tuned ECU flash for the BMW X6M. ECU Tuning is all done through the OBDII port with our iFlash system following these instructions. The MSD85 ECU can be read out and written back to very easily. This also includes the X5M from 2008-2014. Our customer Carlito in the Philippines hooked his red X6M up with our flash. With an almost 80 hp gain and 90 ft/lbs of torque, the 4.4L twin turbo goes into kill mode!
