The BMW X5M is a beast with a 4.4L twin turbo V8.  Cranking out 555 horsepower, this is an SUV that can do more than your average family hauler.  The driving dynamics of this X5M are VERY M like where some even use theirs on road course.  With 500ft/lbs of torque, towing is no hassle either.  As a predecessor to what was to be the office BMW F10 M5, the 4.4L V8 Turbo proved that tuning these engines was no joke in the power they could deliver.  The VR Tuned OBDII performance ECU upgrade for the BMW X5M and X6M is done via the OBDII port with our iFlash system.  You read out the Siemens ECU, send us the file, we do the enhancements, and then email you a new tuned file to load.  With the ECU flash, the E70 X5M gains almost 80 horsepower and 90ft/lbs of torque making this a pure beast!  Our dealer at European Road and Racing in South Carolina recently did this customers BMW X5M and it was an extraordinary difference.  Check out there photos below and see more on the VR Tuned BMW X5M Tune Here.
